A demon is defeated, but something still stirs in Peridot. It's never good for an agent to let their guard down. That's what werewolf detective Colton Fen learns as he finds himself trapped and surrounded by people who want him dead. Their cruel leader will make Colton confess his supposed sins or have his head. Worse yet, his isn't the only life on the line. This Colton Fen Adventure is set between Books 1 and 2 of the Colton Fen series, but can also be read as a standalone.
