Dead In The Water. The Harborview Cafe Mysteries, #4

In a small Maine fishing village, some causes are worth dying for... Tammy Harper's Daily Catch Café is alive with October gossip when environmental activist Paula Henderson is found dead on the rocks at Lighthouse Point. The police call it an accident. The town isn't so sure. But Tammy knows something doesn't add up. Paula had just discovered a legal loophole that would permanently destroy Ron Mitchell's waterfront development-and she wasn't shy about filing the paperwork.
Now she's dead, and Ron's the obvious suspect. Ron's wife has twenty years of resentment over an old affair. Paula's protégé has been hiding connections to Ron's company and can't account for her whereabouts. Ron's own alibi falls apart under scrutiny. And when Ron disappears on his boat, Chief Nash thinks she finally has her killer. But Tammy realizes everyone's been looking at the wrong suspect.
The truth lies not in business deals or environmental battles, but in a moment of desperation and a lifetime of fear. When Tammy finally pieces together what really happened that night at Lighthouse Point, she'll discover that in a small town where everyone knows everyone's business, the most dangerous secrets are the ones people keep to protect the lives they've built.
