"O'Neil is a polished storyteller with a breezy style." 
 
– Marilyn Stasio in The New York Times

"In-Body" uses science fiction to explore the personal debts we owe to others. Touching on PTSD and survivor guilt, it asks how much harm the living should risk in order to make peace with the dead. 

Ex-cop Hank Coughlin leads a double life, helping long-term undercover officers secretly communicate with their handlers. His own undercover career ended in bloodshed and betrayal, so he'll do anything—legal or otherwise—to protect the people who now trust him with their lives.






Vincent H. O'Neil brings a wealth of life experience to his writing. Over the years he has served as paratrooper, a consultant, a risk manager, and an apprentice librarian.

 

A native of Massachusetts, he is a graduate of West Point and The Fletcher School. After writing in his spare time for many years, he won the St. Martin's Press "Malice Domestic" Writing Competition in 2005.

 

His award-winning debut novel, Murder in Exile, was the first book in a mystery series featuring the background-checker Frank Cole. It was followed by Reduced Circumstances, Exile Trust, and Contest of Wills.

 

His mystery novel Death Troupe is the first book in a theater-based mystery series featuring playwright Jack Glynn and the unusual members of the Jerome Barron Players theater troupe.

 

A long-time fan of horror in both literature and film, in 2013 he published Interlands, a Lovecraftian horror novel set in Providence, Rhode Island. The book features graduate student Angela Morse, who is searching the local woods for a lost stone obelisk once worshiped by a colonial-era cult that perished at its feet. The sequel, Denizens, was released in 2015.

 

Most recently, HarperCollins published his five-novel military science fiction Sim War series. Written under the name Henry V. O'Neil, those books are Glory Main, Orphan Brigade, Dire Steps, CHOP Line, and Live Echoes.

His short fiction has appeared in several anthologies, as well as Mystery Weekly, Lovecraftiana, Hypnos, Mystery Tribune, Bourbon Penn, and Scene4 magazines.
