Great show. I mean, outstanding. Good dialogue, excellent acting, terrific pacing... you could hardly ask for more in a play. The play itself was based on the Sign of the Four, the second Sherlock Holmes mystery. However, it wasn't the same as the story, it took just enough of a turn to make it a different story (an enjoyable one) and keep you from the direct answer.
Todd Waite, who has impeccable comedic timing and a countenance similar to Jim Parsons (Sheldon on the Big Bang Theory), was perfectly cast as Sherlock Holmes, but then again, all the roles were very well cast.
The show is done now - they're moving on to the next play (whatever that might be - I can't recall at this time), but should this show make a return to Houston, I think I would find a way to see it again.
The next play I want to see is The 39 Steps. Cross our fingers.
