Ghosts Who Lie

Mourningside Manor, the most haunted house in Gloomwick, has returned all nine of the Town Council’s census reminders, each marked Deceased — not known at this address. So the Council sends you, its new Registrar of Hauntings, to count the household in person, one candlelit sitting at a time.

The trouble is the household: a retired colonel with magnificent whiskers, a lady who finds everything common, a melancholy poet, twin great-aunts who swap names to tease visitors, a butler who announces everyone twice, and many more. Candid ghosts always tell the truth. Fibbers never do. Flickers take turns. Over nine nights they argue, accuse each other and lose the spoons, and only careful reasoning will tell you who is who.

Inside this book:

• 100 original truth-teller and liar riddles in the classic knights-and-knaves tradition, from two-ghost warm-ups to eight-ghost brain-benders
• Clear rules, a worked example and five useful deductions to get you started
• A hint for every riddle, plus a full step-by-step solution that shows the reasoning
• Every riddle checked by computer: exactly one answer, reachable by logic alone, with no guessing
• Ghost portraits on every riddle page, tick boxes for your deductions, and a story told over nine nights with a twist at the end
• Large 8.5 x 8.5 inch pages, printed in black and white

For anyone who enjoys logic puzzles, brain teasers and a good whodunit, and for everyone with a soft spot for spooky, cozy, darkly whimsical things. Book 5 of the Owlbrook Oddities, a series of gothic puzzle books set in the fog-bound town of Gloomwick; each book stands alone.
