A gaslit night. A body discovered. 5 suspects, 5 reasons to lie — and only one guilty conscience before the morning comes.

Deduce cases are logic-grid deduction puzzles: read the clues, eliminate the impossible, and name who did it, where, and with what. This case was verified by a constraint solver as solvable by deduction alone before it was published. The solution is not published here — the only way to know is to work it out.
