The Silent Hour by Michael Koryta

The 4th and last book (2009) in the Lincoln Perry series is somewhat like the rest.

Great plot. Lincoln unlikeable as ever.

Alexandra Cantrell, daughter of a notorious Mafia don, and her husband, Joshua, set up a house for paroled murderers.

Only Koryta dreams up things like this.

Parker Harrison served fifteen years for murder but claims Alexandra’s intervention saved his life. Now he wants to find her–and he’s not the only one.

Lincoln Perry takes the job.
