Ghost Man (Jack White #1) by Roger Hobbs

In a daring operation, two crooks-for-hire rob an Atlantic City casino. But their heist goes horribly wrong, and only one of them makes it out alive. Now he's on the run with $1/2 million vacuum-packed into a bundle the size of a briefcase. Little does he know it's rigged with explosives.

Almost immediately, an expert fixer named Jack is in cross-country pursuit. With less than 48 hours to recover the money, clean up the mess, and--for god's sake--try not to botch the job like he did last time . . .
