Murder On Belle Island - 2020 - 6/10
AKA - Meurtres à Belle-Île

A real estate agent, with a reputation for wife-stealing, is found tied to a menhir, dead.
Mainland detective is sent to assist, just as another murder occurs.
The first half of this is (unintentionally) funny, as the mainlander has no check switch and the damnedest things fly out of his mouth. Such as, he starts flirting with suspect #1, and even makes a romantic date.
Gradually, the nonsense ebbs away, leaving a routine ho-hum procedural.
Compensation, fantastic island scenery.
