What Lake Como Took. A Claire Harmon Mystery, #10

The lake was supposed to be the reward. After the storm-locked ordeal that nearly cost her everything, Claire Harmon finally takes the trip she's been promising herself: Rome, then Tuscany, then the impossibly blue water of Lake Como, on a small-group tour with fourteen strangers who know nothing about her past - and nothing about each other. No old history. No old grudges. Just good wine and Will Tanner beside her the whole way.
Then a landslide seals the only road out of the lakeside village of Varenna, the ferries stop running, and one of the most well-liked men on the tour is found dead at the base of the cliffside path everyone calls the Lovers' Walk. Fourteen strangers, seated together every night for two weeks, become fourteen suspects. Old kindnesses start to look like old debts, and the traveler the group turns against first is hiding a secret of her own - just not the one anyone thinks.
With the road washed out and real police days away, Claire has to find the truth among people she's known for exactly two weeks, and learn not to trust the ones she's grown to like best. What Lake Como Took is Book 10 in the Claire Harmon Mystery series - a storm-sealed, sun-drenched whodunit for readers of Lucy Foley, Liane Moriarty, and Beatriz Williams.
