The 13th in the Inspector Gamache series (2017). Excellent writing, as always.

BUT I am fed up with the absurdity of her plots.

This nonsense must be the most unlikely yet.

Gamache is now the Head of Surete du Quebec — yet finds himself in court risking perjury. Why is never made clear (to me) though it seems to have something to do with saving young Quebecois. From drugs.

Every less likely is a mysterious masked person in black standing in Two Pines. For a couple of days.

Could drugs be smuggled through a tunnel in the church basement? Right after a murder in the same basement?

Readers are expected to believe it.
