A down on his luck guy comes across a small fortune in stolen money dropped after an armored car heist, but the crooks are hot on his trail, in Robert Colby's Run for the Money.
He gives up a dead-end job and flies out to LA to start all over with work and women, only to find out his new girlfriend could be used as leverage against him. This one has crackling action all the way to its denouement.
Colby has been somewhat rediscovered recently for a brace of hard-nosed pulp novels entering reprint, and this is no exception, a tale that becomes more nihilistic as it rockets to its conclusion.
I got this one in a batch of assorted paperbacks and read it quickly on vacation.
