My husband and I both read this book, 6th in the series, on loan from my mother-in-law. The escape of the elderly gentlemen was funny, perhaps the best part of the story.
I didn't really want to read all about that cruelty to animals.
The Gran seemed more prickly and interfering, not as welcoming as earlier in the series.
I thought Lois' description of her family was sad, "Derek's still struggling to be head of the family, Gran is a tower of strength and a bit of an irritation at the same time, Josie and her bloke are doing as well as can be expected in the shop, and the boys are away and I've no idea what they're up to." Somehow the series had lost its homey feel, and the family characters seem isolated and frustrated with each other.
Also Derek and Lois's marriage, once threatened in an earlier book, but generally portrayed as strong, does not seem to be as solid as it had been, as indicated by the ultimatum Derek gave Lois. It shouldn't have taken Lois so long to respond ...
Still, all in all, the mystery was an interesting one to read, and I like Jeems, although having a Jeems is perhaps a bit cliche.
