An abandoned baby at a bus depot. Seven weeks old. No leads.
The Case of the Pennsylvania Gun: Holmes and Watson travel to the Sussex countryside to fish — literally — for clues in a shotgun murder of John Douglas, what Holmes calls “The Case of the Other Dumbbell”. Holmes slides down a bannister in the course of his investigation. He not only deduces who the murderer is, but also who the victim is.
The first part of the show is a faithful retelling of Holmes and Watson’s meeting as in “A Study in Scarlet” until Holmes invites the good doctor to their first murder investigation. Lastrade has it all wrong, of course, picking the most likely suspect, Peter Cunningham’s secret bride, a “jailbird”.
