Ludwig Solves an Unsolveable Case in the Season’s Penultimate Episode

How do you solve an unsolvable puzzle?

That’s the case Ludwig is trying to crack in Season 1’s penultimate episode. Ludwig and Carter are called to investigate the apparent suicide of a private school headmaster, Mr. Durose (Christopher Parramore). The case resonates with Ludwig because it’s where he went to school, and his beloved math professor, Mr. Todd (Derek Jacobi), is still on staff.

Even Carter doesn’t think it’s an open-and-shut case this time. For one thing, the headmaster’s typed suicide note is riddled with grammatical errors. For another, the desk the headmaster allegedly stood on before hanging himself is in perfect order—not a piece of paper out of place. “If it was a murder, then how did the killer get out? The windows are painted shut, and the door is locked from the inside,” Simon wonders.
