From the Publisher:
The messages were coming in; coded messages that John Creevey should never have seen. Was it a major spy ring? A drugs gang? Or a protection racket? Whatever they were, to John Creevey the messages were a lifeline - a means of getting back his wife and harming the man who seduced her.
