Down Comes the Night — Frank Zafiro

A battered Sam and Rachel realize they must take a sabbatical from the grift for an extended time to escape the vengeful mobsters hounding them. To survive, they must raid all of the honey pots they've left scattered across the country. Some may be watched by the mob, others will require a con to recover. They go after these caches of cash with danger—and death—lurking at every turn.
