John Dickson Carr - The Mad Hatter Mystery

I have been reading John Dickson Carr's Doctor Fell novels following my discovery of the later book The Hollow Man last year. That is considered one of the greatest "locked room" mysteries, and Carr's other works tend to work on a similar principle - a ludicrous or impossible situation is worked out by Fell who improbably refuses to divulge any information on his method until he has worked it all out. I suspect any genuine police officers who worked with Fell would have arrested him for "obstructing the course of justice" or some such misdemeanour.

Of course for the reader this is excellent as it allows them to concoct their own theories only for them to inevitably be destroyed by Fell's own explanation. The Mad Hatter Mystery is the second volume of Fell's stories, and follows this pattern closely. In fact, despite the blurb saying that the books can be "enjoyed in any order", this book does follow on relatively soon after the first story. It is better to read it in order in my opinion. Two seemingly separate sets of events are brought together in a murder. One is the repeated, and public, stealing of hats and their placements in public places. The second is the discovery and then loss, of a priceless and unknown short story by Edgar Allan Poe. 

The details of what takes place matter little, and their divulgence here might spoil the story for future readers. But I found the story incredibly complicated. There were a plethora of characters, many of whom appear to only exist to complicate the main story. The real joy in the book is the setting and the depiction of the police investigation for the murder takes place in the Tower of London and the police search takes our heroes across 1920s or 30s London. We get quite a few insights into drinkers' culture and the lives and loves of our upper-middle class characters. 

But I did not get any satisfaction from the ending. I had little invested in the characters and the central mystery of the Hats was disappointing. A few hours after reading I am not sure I can tell you what and why the murder actually took place. That might be stretching the truth a little, but the book lacked the dark overtones of the other Fell novels.
