When Corie Geller asked her parents to move from their apartment into the suburban McMansion she shares with her husband and teenage daughter, she assumed they'd fit right in with the placid life she'd opted for when she left the FBI.

But then her retired NYPD detective father gets a call from academic April Brown - one of the victims of a case he was never able to solve. When April was five, she emerged unscathed from the arson that killed her parents. Now, two decades later, someone has made an attempt on her life. It takes only a nanosecond for Corie and her dad to launch a full-fledged investigation.

If they don't move fast, whoever attacked April is sure to strike again. But while her late father, Seymour Brown, was the go-to money launderer for the Russian mob, April Brown has no enemies. Well-liked by her students, admired by her colleagues, who would want her dead now? And who set that horrific fire, all those years ago?

The stakes have never been higher. Yet as Corie and her dad are realizing, they still live for the chase. Savvy and surprising, witty and gripping, Bad, Bad Seymour Brown is another standout hit from the beloved Susan Isaacs.
