Cap Fog 4: Cap Fog and J.G. Reader

That there should be an attempt to kill him did not surprise Mr. J. G. Reeder. In the course of his career, the mild and gentle detective had incurred the enmity of many dangerous and desperate criminals, and one of who might be seeking revenge.

There was only one man capable of inspiring such fear among the British underworld that it caused the blanket of silence facing Mr. Reeder. But old Mad John Flack was dead! Or was he?
Before Mr Reeder could solve the mystery, he was grateful for the support of Alvin Fog, grandson of the legendary Rio Hondo gun wizard, Dusty Fog. The youngest man ever to attain the rank of captain in the Texas Rangers, said to be the most deadly combat pistol shot of his generation, Alvin Fog needed all his skill to survive when he and Mr. Reeder stumbled on the solution!
