Description:

The private-eye business was slow, so Anthony Rome when skin-diving. But instead of treasure he found a woman's naked body – her feet embedded in a block of cement! She had last been seen alive at a ritzy party given by wealthy heiress Gretchen Forrest. Also at the party had been bigtime tough Al Mungo, who claimed he'd quit the rackets. Anthony Rome started asking questions. And one morning he woke up swollen, bruised and beaten. He hadn't learned much – except that Mungo hadn't lost his heavy touch, and that somewhere along the line, Mungo had picked up a very special interest in lovely Gretchen Forrest!
