House witness
(Book)

In House Witness, the twelfth novel in the Joe DeMarco series, Mike Lawson puts his likable protagonist on the trail of a different kind of fixer--one whose job is to influence, and sometimes disappear, witnesses in seemingly airtight criminal cases. Minority Leader of the House and DeMarco's long-time employer John Mahoney has kept more than one secret from his wife over the years, but none so explosive as this: He has a son, and that son has just been shot dead in a bar in Manhattan. Mahoney immediately dispatches DeMarco to New York to assist prosecutor Justine Porter, but with five bystanders willing to testify against the killer--rich-boy Toby Rosenthal--the case seems like a slam-dunk. That is, until Porter begins to suspect that someone is interfering with those witnesses, and that this may be connected to a pattern of cases across the country. Is there someone who is getting witnesses out of the way when the fate of a wealthy defendant is on the line? With the help of Porter's intern, as outrageously smart as she is young, DeMarco becomes determined to follow that question through to its violent resolution in what turns out to be this series' most unexpected plot yet.
