This is the first Anthony Berkeley book i have ever read, and I enjoyed it a lot. I am a fan of the cozy mystery, and the Golden Age of Crime novelists but somehow had not heard of Berkeley before, although I have at least heard of Francis Iles, one of the pseudonyms that he has used. Guess I have been missing out, because this was a very innovative story that piled on twist after twist to keep me totally engrossed.

The story revolves around a murder case which has baffled the police, and its taken up by the Crimes Circle, a club that Sheringham has started. The approach they take, though, is not of working together to solve the crime, rather its a competition to see which one of them is able to solve it. Let the Murder Olympics begin!

Almost the entire novel is basically each of the members giving the speech thats usually at the end of a cozy mystery, where the detective explains his/her reasoning to the reader and the key characters in the story. Each of the Crime Circle members present a pretty good case based on their deductions, which the next member then starts breaking down based on their own deduction. Of course, to successfully be able to build and then break the same crime down, there have to be some details that are kept from the reader but that's not unusual in mysteries. Overall, I highly enjoyed The Poisoned Chocolates Case and I will definitely read more of Berkeley's books.
