Diary of a Small Fish by Pete Morin
When Paul Forte is indicted by a federal grand jury, everyone suspects prosecutor Bernard (don’t call him “Bernie”) Kilroy has more on his mind than justice. Then the FBI agent in charge of Paul’s case gives him a clue to the mystery: Kilroy is bent on settling an old family score, and he’s not above breaking the law to do it.
Paul is already dealing with the death of his parents and divorce from a woman he still loves. Now, with the support of an alluring grand juror, Paul must expose the vindictive prosecutor’s own corruption before the jury renders a verdict on his Osso Buco.
