Holmes and Watson at the theatre

I saw a new-ish Holmes play, written by Jeffrey Hatcher. (It's a couple of years old, but new to the DFW area.) The premise is that 3 years after "The Final Problem," Watson receives a summons to a mental asylum where three patients claim to be Sherlock Holmes. He has to go there to debunk the fakers. It is a mystery thriller with plot twists and different accounts of how Holmes survived Reichenbach Falls. I enjoyed it a lot, and I got right away the reference to Irene Adler and the smoke-rocket used to steal a document. It's great fun, perfect for the summer.
