#29 The Second Husband by Kate White

Quote
Recovering from the unsolved murder of her first husband, Derrick, thirtysomething Emma Hawke has built a new life with Tom, a handsome, successful, and loving widower who finally makes her feel safe again.

Then one day a police detective shows up at their house on the Connecticut shore, asking questions about Derrick's death. Emma was sure she'd been cleared in the days after the tragedy. So why is law enforcement taking another look now--and questioning the timing of her relationship with Tom? She hadn't even met him until after Derrick's death.

Average thriller with a so-so ending.
