Kilmer meets with his editor and is urged to write an article about his experiences. After its publication, he is hounded by crank callers. One caller, Allison Tynes, claims to be Jenn's twin sister. Allison travels to New York and indeed looks, acts, and even speaks like Jenn (Kilmer is told her real name is Julie). The duo decide to work together.

Clues begin to appear including a missing phone bill which points the pair in the direction of Susan Donovan and Dr. Phil Garber, a psychiatrist who tells Richard he treated him three times for a delusion he was having about a woman named Jennifer. (Kilmer does not recall any of these appointments.) Garber also reminds him of his interactions with Sean Lassiter who was the CEO of a pharmaceutical company with duplicitous dealings with the FDA and that Lassiter had vowed revenge after his investigative report.

David Rosenfelt, the author of the Andy Carpenter series, has written a standalone medical thriller with elements of Alfred Hitchcock and "The Twilight Zone." Rosenfelt combines an engaging writing style with vivid characterizations and subtle, dry humor to enhance the story of Richard Kilmer his protagonist and narrator. On Borrowed Time was five stars till the conclusion which was rushed, confusing and left too many loose ends.

While certainly not his best work and somewhat implausible, On Borrowed Time is still an enjoyable read and certainly worth your time if only as a diversion.
