From the back of this book:
In this delightful second installment in Alexander McCall Smith’s bestselling detective series, the irrepressibly curious Isabel Dalhousie gets caught up in a highly unusual affair of the heart.
When Isabel is asked to cover for vacationing Cat at her delicatessen, she meets a man with a most interesting problem. He recently had a heart transplant and is suddenly haunted by memories of events that never happened to him.The situation piques her insatiable curiosity: Could the memories be connected with the donor’s demise? Naturally, Isabel’s friend Jamie thinks it is none of Isabel’s business. Meanwhile, Grace, Isabel’s housekeeper, has become infatuated with a man at her spiritualist meeting, and Cat brings home an Italian lothario. That makes for some particularly tricky problems–both practical and philosophical–for Isabel to unravel in this enormously engaging and highly unusual mystery.
There's a reading group guide here, but I haven't looked at it.
I like the characters in his books. The books themselves are relatively slow-moving and are well-paced. I always look forward to the next one, and I do have several more of his books on my weighed-down to-be-read shelves. It's a comfort to have unread books that I can count on to be thoroughly enjoyable.
