Is this . . . the last book in this series? I honestly can't tell. There's a lot of plot threads that seem to reach an end here, but maybe the series is just headed in a new direction?
Not quite as funny as some of the previous ones, but with a lot of interesting content. And one annoying habit on the narrator's part. There are three doctors heavily featured in this book, but only the male one is consistent referred to as Dr. The two women with the same credentials are consistently referred to by first name with no title. I know that's a pretty minor complaint, but it really got on my nerves.
Whatever, hopefully the FBI agents will show up more in the future if there are more of these.
