The Murder Inn by James Patterson & Candice Fox

Returning to the rocky shores of Massachusetts, Bill Robinson has to solve a string of murders if he wants to save his inn. Murder House, The Beach House, Honeymoon --James Patterson is the master of thrills on the water.

The Inn at Gloucester is the lone structure on a rocky Massachusetts shoreline. Former Boston police detective Bill Robinson runs the place as a refuge from life’s cruel disappointments. When two strangers arrive for a temporary stay among the permanent residents, they’re welcomed with no questions asked by Sheriff Clayton Spears, who lives on the second floor. 
 
There’s another new resident in town. A crime boss. And he doesn’t like the close watch Robinson and Spears keep over Gloucester.  
 
Local criminals are turning up dead. The Inn is under surveillance. Teaming up with Sheriff Spears and three fearless residents—Army veteran Nick Jones; former FBI agent Susan Solie; and mysterious groundskeeper Effie Johnson—Robinson begins a risky defense of his town, his chosen family, and his home.
