These 12 stories consist of a “club” of men, called the Black Widowers, who meet once/month for conversation and solving problems. Male black widow spiders eat their spouses, so needless to say, the men don’t invite their wives! Each month, one man is the host, who may invite a guest of his choice. In each story, the guest is asked to justify his existence.
Inevitably, one of the men, or the guest, comes up with a problem, which the men, the guest, and the waiter, Henry, who has also become a member of the club, must solve. It is often Henry who solves the problem, after listening to the other men discuss the case.
The stories are easy to read, make one think a bit, and are moderately interesting. I, personally, didn’t really enjoy the stories. I felt the “solutions” to the problems were far-fetched or didn’t make a lot of sense. The stories did make me think a bit, so for that they weren’t so bad.
