The Velvet Hammer!

"Barney Garrett and Jack Marsh are two members of an extraordinary profession. They are part of the Special Squad, a unit of the C.I.D., which is armed and prepard for an eventuality at a moment's notice.

"But though Garrett and Marsh are intelligent, dedicated, expert marksmen, and rained in judo and karate, they are, nevertheless, men with their own private dramas - Garrett with his promiscuous wife, and Marsh with his ever-feuding girl friend.

"THE VELVET HAMMER is an authoritative novel dealing with a section of the police force not generally known to the public. It is also a close and revealing study of two men who have to reconcile their domestic happiness with a job involving murder, drugs, blackmail and prostitution."
