Criss Cross

Could a ghost from his past take everything away from Alex Cross?
Mere hours after witnessing the execution of a killer he helped put behind bars, Alex Cross is called to the scene of a copycat murder. A note signed "M" rests on the corpse: "You messed up big time, Dr. Cross."
Was an innocent man just put to death? As the executed convict’s family launch a vicious campaign against Cross, his abilities as a detective are called into question.
The enigmatic "M" lures Cross out of Washington, DC to the sites of multiple homicides, all marked with distressingly familiar details that conjure up decades-old cases and Cross family secrets.
Details that make it clear M is after a prize so dear that - were the killer to attain it - Cross’s life would be destroyed.
