Substratum A Jasper O'Malley Novel

Deep beneath the streets of Detroit, someone - or something - is picking off the miners of the Detroit Salt Combine. The company appears to be more concerned with the protection of their equipment than with the safety of their employees, so the miners take it upon themselves to approach the Attican Detective Agency to find out what's happening to their co-workers. Jasper O'Malley, an agent with a reputation for getting things done (at great cost), is assigned to the case. Teamed with Sadie Dupree, a geological expert, and Amelia Rio, an ace driver for one of the Organized Crime families, Jasper ventures underground to investigate the fate of the miners. But there's another factor operating within the labyrinth of tunnels, a factor that would kill to keep its illegal operations undiscovered. And still another factor has infiltrated the hired detective's own group. Yes, there's a Judas working with Jasper, a traitor who knows the secret of the mine, and who will stop at nothing to keep the mine's secret. Can Jasper track down whom or what is responsible for the miners' disappearances, or will he and his one true ally suffer the same fate as the unfortunate workers?
