Once burned...By rights, the horrific schoolyard crime should have been laid to rest twenty years ago. An alleged perpetrator confessed and now is growing old behind bars. But the case still haunts ex-Detective Chief Inspector Carol Chamberlain — and she has asked DI Tom Thorne to uncover a disturbing truth that lies buried in the ashes.A series of brutal gangland slayings — each victim found with an X gouged into his back — has Thorne plunging into the fires of a deadly turf war, as he attempts to tie together the threads of perplexing crimes separated by decades. But time is rapidly running out in his search for a copycat who revels in blood and pain — because the body count keeps rising... and someone has carved an X into Tom Thorne's front door.
