A Study in Scarlet

A rather dull read that feels less like a mystery you are suppose to solve (or, at the very least, follow along with) than Doyle deliberately coming up with overcomplications (the poison pills, the unknowning accomplice, etc) and hiding information for the sake of it (the content of Holmes' telegrams, the detail about the cab horse). Also, cutting away from the story for a multichapter flashback to justify the killer's motives sure is... A choice.
