Confronted by the first murder suspect of his early career while visiting his hometown, FBI detective Amos Decker reexamines startling connections to another crime that make him question if he arrested the wrong man years earlier.

Amos Decker and his FBI partner Alex Jamison are visiting Decker's hometown of Burlington, Ohio, when he's approached by Meryl Hawkins-- the first person Decker ever arrested for murder back when he was a young detective. A dozen years in prison have left Hawkins unrecognizably aged and terminally ill, but one thing hasn't changed: he maintains he never committed the murders. Could it be possible that Decker made a mistake all those years ago? Digging into the old case, Decker finds a startling connection to a new crime that he may be able to prevent, if only he can put the pieces together quickly enough. -- adapted from jacket.
