Five Million Reasons: Sometimes Money Isn't Everything.

Eva Blalock did not embezzle - She stole five million dollars in cash from the contracting company where she worked.
Her employer, R.L. Standridge, doesn't want the authorities involved because the money isn't actually legitimate earnings for the business and he is offering a five percent reward to any private investigator who will return his loot.
Doris Blackmon is not a private investigator, but she has read her Dad's 1930s detective novels and that should be good enough.
Right?
She thinks so.
Doris involves her soon-to-be ex-husband, against his better judgment.
Together they manage to convince the contractor that they can recover the money.
Doris' brother, Boris, learns of the purloined millions, and wants his share.
Her coworker, Ralph, has also picked up the scent, and he wants it all.
The mad race halfway across the country is sometimes hilarious, sometimes sad, sometimes sexy, and sometimes dangerous, but always an adventure that you just can't put down until the very end.
