A fog-laden evening. An invitation that proved fatal. The manor holds the answer, if only the detective can read its shadows.
This Junior case is set in Blackwood Hall and puts 4 suspects, 4 rooms, 4 weapons, 6 clues on the board. 4 detectives filed a correct verdict on the day it ran. Detectives who cracked it took a median of 2 minutes.
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.
