'Storytelling at its very best!' Michael Connelly

When you have as few friends as private investigator Lennox does, you can't afford to lose any. When you do, someone has to pay.

Quiet Tommy Quaid is one of Lennox's few friends in Glasgow. Lennox appreciates Tommy's open, straightforward personality - even if he is a master thief.

When Tommy is flung to his death from a factory roof in front of Lennox's eyes, Lennox discovers just how wrong he was about Tommy's quiet life.

It seems Tommy knew a secret, and it cost him his life. But for once, Quiet Tommy didn't go quietly. His secret concerned people above the law - people in some cases who are the law - and so now, from beyond the grave, he leaves a trail for Lennox to follow to ensure justice is done. For once, Lennox is on the side of the angels. But he is an avenging angel, and in brutal Glasgow, justice has to get bloody.
