Master Detective · 11 June 2026 · Blackwood Hall
The victim is Colonel Alistair Drummond. Returned from the Continent with a distinguished record and a scar that maps across his left cheek like a river on a bad chart. He sleeps lightly and speaks seldom.
This Master Detective case is set in Blackwood Hall and puts 4 suspects, 4 rooms, 4 weapons, 10 clues on the board. 2 detectives filed a correct verdict on the day it ran.
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.
