The Silent Seven — Maxwell Grant

WHO KNOWS WHAT EVIL LURKS IN THE HEARTS OF MEN?

A violent crime wave swept New York--ingenious, well-planned escapades masterminded by the Silent Seven, a vicious underworld conspiracy. Hooded criminals, meeting in secret, known to each other by an ancient ritual and matching scarab rings, they plotted to terrorize the city.

Detective Cardona was baffled. First one murder, death by a poison pin prick; then another, a cold- blooded execution. The sole clue to both, a pair of dice showing seven. He knew only one man could penetrate the inner sanctum of this den of evil--The Shadow. Moving with uncanny stealth, the master crimefighter carefully lays a brilliant trap. If his cunning were enough to defeat these evil angels, the last laugh, that eerie chuckle, would be his once again!
