Silver Blaze done right at last

In the Elementary episode the Marchioness the writers finally made good on Doyle's biggest gaff in the Holmes cannon. Doyle had done no research on horseracing and suggested a horse could be entered at the last minute with no verification of identity "gentleman's honor" and all that. In the episode Silver Blaze was a valueable stallion out to stud, and secretly dead. A substitute silver blaze was being used for semen sales to unsuspecting breeders. Nice to see the writers of the updated Sherlock Holmes getting it right.
