Carole and her children, Brianna and Louis (or names of that nature), are visiting the island. Though the husband/father, Gordon, is off somewhere with some vague "family issues" excuse. Brianna's the one who, in an earlier story, had played dress up with Leger, as in dressed Leger up.
While interacting his family, Leger overhears them mention a crime that had occurred right near them. In the Loch. A drowned man, who had been pushed in apparently. Annabella's quite upset. Especially considering Carole and the kids are out at the loch at that exact moment.
Then Carole, much later, goes for a really really long walk. By herself. As in, she left at night and in the morning she still hadn't returned. So, two mysteries to solve for Leger. The case of the drowned man, and the case of the missing woman. Though this time he actually has Bob's help, since Carole's a dog person, and Bob's upset at her disappearance.
I rather liked this one. Good solid story.
