Mammon — Dan O'Shea

Ex-Marine, Nick Hardin, heads back from a decade in Africa to his hometown, Chicago, with $100 million in blood diamonds stolen from an Al Qaeda's financing pipeline. His retirement plan? To cash out through a Chicago Mossad contact and head for the beach. But soon, Hardin's stuck in Chicago with diamonds he can't sell and a series of hit men, mobsters, and a Washington off-the-books black ops team on his tail. The resulting body count leaves Chicago detective John Lynch trying to find connections among the victims, while simultaneously solving the murder of a dead infectious disease expert who'd drafted a biological weapons plan that could turn Chicago into a ghost town.
