Ta-Da! Episode 21 sees Josh and Scott bring their 20-month canonical tour to an end with a final hurdle over the remaining stories of "The Case-Book" and reach the summit of Mt. Sherlockia. This final reading episode has got it all (for better or worse): jealous wives, monkey-men, dastardly jellyfish, suspicious dogs, circus tragedy and vengeful decorators. The heavy-lifting now done, "Lighting the Pipes" will return with its finale in Epsidoe 22, Bowman & the BFG's "Guide to the Canon".
