A series of brutal murders. A lost treasure. And the one woman Wren never wanted to see again. Abraxis Wren, Sharn's most notorious inquisitive, hasn't had a case in months when his ex-wife shows up on his doorstep, framed for the murder of a man she was hired to protect. She's the last person he wants to help, but the trail of bodies—and the connection to an elite squad of killers from the Last War—is too intriguing to resist. With his assistant Torin in tow, Wren races to piece together the blood-stained clues. Only he can save the next victim of the Black Brigade's deadly tontine... and find the treasure that belongs to the last soldier standing.
