Kill the Boss Good-by, by Peter Rabe (epub/Kindle/pdf)
Pander wore dark glasses and fancy suspenders and he moved into the San Pietro rackets like a sandblaster gone berserk.
Fell, the boss, was mysteriously away and Pander grabbed the chance to bury his hands in the heavy money. Then Fell came back. At his side was Cripp, the human adding machine with the beautiful face and the twisted leg.
With them came murder... wholesale.
