This was a really involved plot dealing with American currency, taking Flynn all over America and even to Russia. I only have two more books left in the Flynn series. ( )

Flynn learns the value of money

On medical leave from the Boston Police Department, the eccentric Police Inspector and offbeat operative, Francis Xavier Flynn might have his most perplexing assignment yet. Someone is giving away hundreds of millions of dollars, and Flynn has to find out who in a hurry. As he races from Texas to Las Vegas, from Massachusetts to Russia, Flynn quickly discovers that this is not the pastime of an eccentric billionaire, nor is it a nefarious counterfeiting scheme. Someone is looking to wreck the nation’s economy and bizarrely enough, spending a lot of money to do it. With every lead going nowhere, Flynn’s most dizzying logic is put to the test, but the clue he needs could be somewhere in his own murky past.
