Ex-Con, by Stuart Friedman (epub/Kindle/pdf)
He was free now. But his wife was gone. Somewhere the con men were using her as bait--to force him back into their criminal syndicate. And in his violent search through the flea-bitten jungle of hoods and vice dolls he met the beautiful nymphomaniac who swore to help him. Then he learned her awful price-- He had to yield to her naked savagery or be framed for a brutal killing!
