Idle question
If you were going to insert a detective into one of Shakespeare's tragedies, would you go for a character like Philip Marlowe [1] or one like Miss Marple [2]? The Chandleresque character strikes me as more likely to live to the end of the story but Marple could be played as a kind of wise fool.
1: I started off with Hammett's Continental Op but Marlowe's speech patterns are more amusing to me.
2: Or Tommy and Tuppance if you want the detectives to have a confederate with which to converse.
