'Elementary' Clue-cap: Sherlock and Watson Run in Circles, then 'Solve for X'
A man named Felix Soto is murdered, and a mugger — who happened to be in the wrong place at the wrong time — is left for dead, unlikely to ever wake up.
Sherlock and Watson encounter their first set of clues:

Clue 3: A photo of a man in a book — in which P versus NP expert Tanya Barrett (Lynn Collins) profiled Felix and other P versus NP fanatics — includes a chalkboard with handwriting matching that of the second math genius who wrote on the wall.
