But that all changes when Paladin finds a box with a note, a box she believes contains a bomb.

Spade and Paladin must hurry to save the convention before the police arrive. The conundrum? Figure out who sent the bomb—before they lose their lives trying.

"I hope to read many more stories about Spade and Paladin."
