Death's Angel is a Bantam TOS novel, written by Kathleen Sky. First published in April 1981, it was the last original Star Trek novel published by Bantam Books.

While transporting Federation ambassadors to a Romulan peace negotiation, a series of unexplained murders takes place aboard the USS Enterprise – and Captain Kirk is the prime suspect.


From the book jacket
The U.S.S. Enterprise undertakes a highly sensitive mission, ferrying ambassadors from across the Federation to controversial peace talks. One by one, the opponents of the proposed détente with the Romulans are murdered – victims of a mysterious Angel of Death. And the killer may be an Enterprise crew member – maybe even Captain James T. Kirk

During an away mission to Delta Gamma IV, Captain Kirk and the USS Enterprise crew encounters a field of blue flower-like organisms. These "Oz Poppies," as they are nicknamed, reproduce by emitting a cloud of spores. The away team is caught in a cloud of these spores, and three of them perish before Dr. McCoy discovers a cure. The six remaining members of the away team (including Kirk, Spock, and M'Benga) remain in an unexplained coma for ten days after the exposure. They awaken suddenly with no apparent side effects – except that four of the six crewmembers no longer dream.

The Enterprise is routed to Starbase 7 to pick up a diverse group of thirteen ambassadors, led by Ambassador Sarek. The ambassadors are heading to Détente Station One for peace talks with the Romulans. Several days into the journey, Ambassador Agnatha is found dead of apparently natural causes. Two days away from Détente Station One, Ambassador Neko is found dead in his quarters, also of apparently natural causes. Both of the deceased ambassadors were among the most outspoken opponents of the treaty with the Romulans, so a suspicious Kirk asks Starfleet for help. Starfleet places the ship under quarantine and assigns a member of the Special Security Division, Colonel Elizabeth Schaeffer, to investigate the deaths.

A mysterious creature known as the "Angel of Death" is visiting the remaining ambassadors, warning that if they do not support the peace treaty with the Romulans, they will die like Agnatha and Neko. This Death Angel appears to each ambassador in the form of the mythological bringer of death for their culture. Col. Schaeffer believes Ambassador Naja of Dalzell is the next likely target after he receives a warning from a glowing winged serpent. She spends the night guarding him in his quarters, only to witness the aged ambassador dying peacefully in his sleep.

A fourth ambassador, Rovar of Hemiptera, is torn to pieces in his quarters after giving a vehement speech against the Romulan peace treaty. Guards were present outside his door during the entire attack, but no one is seen entering or leaving. Out of options, Col. Schaeffer turns to the supernatural for an explanation. Through interviewing the remaining ambassadors, she discovers that Captain Kirk was seen outside Ambassador Agnatha's quarters shortly before his time of death. Kirk remembers seeing the two witnesses in the corridor outside Agnatha's quarters – but he maintains it was only a dream and that he was never actually there.

Of the six surviving members of the Delta Gamma IV away mission, only Kirk and Spock have retained the ability to dream. Col. Schaeffer interrogates Spock and discovers that he too has had a dream that was not a dream. In his case, he was engaging in sexual relations with a female lieutenant aboard the Enterprise while she was in a dream state.

Dr. McCoy determines that the Oz Poppies reproduce by passing spores along to a race of mice with telepathic abilities, who then deposit the spores elsewhere in the course of their dreamed travels. He and Col. Schaeffer theorize that the ability to project the subconsciousness outside the body during REM sleep was unlocked in Kirk and Spock by the infestation of the spores from Delta Gamma IV. Of the six infected crew members, only Kirk and Spock have a high enough psi factor (or esper rating) to remember their spore-induced dream travels. They believe one of the remaining four crewmen may be projecting the Angel of Death apparition without being aware of it.

During an onboard debate about the Romulan détente, Dr. McCoy gives an impassioned speech against the treaty. Col. Schaeffer is convinced that this will result in a visit from the Angel of Death, and stands guard inside Dr. McCoy's quarters that evening. She witnesses the appearance of a white-robed Terran Angel of Death, whom she recognizes as an astral projection of Dr. M'Benga. Spock and Kirk are able to tap into their spore-derived projection abilities to create an image of a god-like being that convinces the Angel of Death to spare McCoy's life. M'Benga is given treatment to prevent the reoccurrence of the projections, and the Romulan negotiations continue on schedule.

Memorable quotes

"There must be peace in the Universe, there must be a détente between the Romulans and the Federation, and eventually between the Federation and the Klingons. We have had enough bloodshed. I am tired of bloodshed. I grieve at the bleeding bodies I must deal with day after day. I am the Angel of Death."

- Dr. M'Benga, while manifested as the Death Angel

Background information

  • This novel marked the end of an association that began with the James Blish novelizations in the late 1960s. Pocket Books, which had already been awarded the Star Trek novel rights at this point, would launch its own series of original novels two months later with The Entropy Effect by Vonda McIntyre.
  • This is Kathleen Sky's second Star Trek book. Her first was Vulcan!.
  • The novel was reprinted by Titan Books in 1995 as part of their Star Trek Adventures series.
  • Though the stardate is given at several points in the novel, the year is never explicitly stated. Ambassador Sarek makes several references to his stay on the Enterprise in TOS: "Journey to Babel", which occurred in 2268. This places the year of this book between 2268 and 2270, the end of the first five-year mission.

Crew of the USS Enterprise

James T. Kirk 
Captain of the Enterprise and survivor of the Delta Gamma IV spore infestation. The residual effects of the infestation left him with the ability to project his subconciousness while sleeping, which made him a prime suspect in the murders of the ambassadors aboard the Enterprise. The aftereffects also left him in a heightened emotional state, during which he made an unsuccessful proposal of marriage to Elizabeth Schaeffer. He maintained a staunchly neutral position on the Romulan peace treaty.
First Officer of the Enterprise and survivor of the Delta Gamma IV spore infestation. During his spore-induced projections, the Human part of his subconsciousness initiated sexual relations with a member of the crew, an event which caused his waking self much distress.

Ambassadors traveling aboard the Enterprise

Agnatha of Jezero 
A lamprey-like being who required a special tank to survive aboard the Enterprise. He was a strong opponent of the peace treaty until his death.
Damu of Chiroptera 
An ambassador who reminded Capt. Kirk of a Terran vampire, due to his appearance and his species' custom of taking nourishment from mammalian blood. The inhabitants of Chiroptera harvested their blood from stock animals, as opposed to killing for it like the vampires of lore. Damu was neutral on the issue of the treaty.
Edentata of Tandenborstel 
A retiring armadillo-like ambassador who kept to himself during the entire voyage. His position on the treaty was neutral.
Hotep of Djoser 
A polymorphite whose slight shape-changing abilities were directly related to the amount of energy he consumed. He was neutral in regards to the peace treaty, as his sole interest in this mission was the amount of food he could eat.
Karhu of Hanaja 
A large bear-like ambassador who intentionally magnified his ursine characteristics to appear less threatening. He was in favor of the peace treaty.
Naja of Dalzell 
A feathered snake-like diplomat who was opposed to the peace treaty, partly due to his dislike of Romulans. Before the truth of the Death Angel was discovered, his death was attributed to his advanced age of 157 years.
Neko of Gyuunyuu 
A large grey felinoid with violent tendencies who was strongly opposed to the Romulan treaty, partially because of his extreme dislike of all Vulcanoid species.
Rovar of Hemiptera 
An insectoid who had a strong dislike of the Romulans and therefore opposed the peace treaty. He died of massive self-inflicted wounds after a visit from the Angel of Death.
Sirenia of Cetacea 
An amphibious humanoid who was romantically involved with Ambassador Agnatha. She was in favor of the peace treaty.

Si-s-s-s(click) of Gavialian 
A blue crocodilian who supported the peace treaty. As is customary of his people, Si-s-s-s(click) enjoyed "persona games," in which he would adopt the characteristics of a specific fictional character or genre. During his stay on the Enterprise, he adopted the personas of Don Juan the romantic, Sherlock Holmes the detective, and Sam Spade, a character from an archaic Terran detective film called The Maltese Falcon.
Spiracles, a Gyomorian 
A slender, winged creature who suffered from heavy oxygen intoxication in the atmosphere of the Enterprise. His people cocoon into a chrysalis form when threatened. Originally neutral in regards to the peace treaty, he became a supporter of it after his visitation from the Angel of Death.

During her stay on the Enterprise, she became romantically involved with Captain Kirk and decided not to renew her marriage contract with Alexis Schaeffer.


Amanda Grayson 
The mother of Spock and an old friend of Colonel Elizabeth Schaeffer. Schaeffer used her pheromones to mimic Amanda's scent in an effort to soothe a distraught Spock.
Angel of Death 
A psychic manifestation of M'Benga's subconsciousness that appeared to each ambassador in the guise of the mythological harbinger of death of their culture. The Angel of Death killed the ambassadors through the power of suggestion, as opposed to actual physical means. This manifestation was terminated shortly after stardate 6982.3 as M'Benga began receiving treatment and counseling for the aftereffects of the spores.
Marmaluke of Antares
