Shanahan says Stevenson (Treasure Island, The Strange Case of Dr.Jekyll and Mr. Hyde) wrote his short story trilogy ''The Suicide Club'' ten years before Doyle debuted ''A Study in Scarlet,'' but the two are a good match. Both feature adventurous leaders with sidekicks who have military backgrounds.
Alley Company actor Todd Waite is back as Sherlock Holmes. ''The great thing about Todd is having played the character, he really has an affinity for him,'' says Shanahan. ''He's very protective to make sure the character is not made fun of, is not a superhero, is not a pompous fool; he fleshes out a person who is troubled by his genius — and it's difficult to be Sherlock Holmes — and he struggles with it.'' Shanahan points to the strength of the Holmes character in that while so many different versions of him have been done and he’s been moved in time so often, the essential nature of the man, his intellect and his abiding strong friendship with Dr. John Watson still come through. ''The character can survive all of that,'' he says.
