A fascinating, festive mystery about a renowned puzzle tasked with solving the most deadly puzzle of all…

On December 1st, renowned puzzle setter, loner, and Christmas curmudgeon Edie O’Sullivan finds a hand-delivered present on her doorstep. Unwrapping it, she finds a jigsaw box and, inside, six jigsaw pieces. When fitted together, the pieces show part of a crime scene – blood-spattered black and white tiles and part of an outlined body. Included in the parcel is a message: ‘Four, maybe more, people will be dead by midnight on Christmas Eve, unless you can put all the pieces together and stop me.’ It’s signed, Rest In Pieces.

Edie contacts her nephew, DI Sean Brand-O’Sullivan, and together they work to solve the clues. As the body count rises, however, Edie knows that she has the knowledge to put together the killer’s murderous puzzle.

Only by fitting all the pieces together will Edie be able to stop a killer – and finally lay her past to rest.
