Synopsis: How do you catch a killer in a castle with 144,000 back doors? The scene of the crime: a party at Castle Perilous. The victim: a nobleman who is certainly not the life of the party. The body is soon indentified as the magic-dabbling viscount named Oren - but a corpse by any other name still smells of foul play! At any rate, mystery loves company, and everyone at Castle P. is scrambling for clues, alibis, and the murder weapon itself. Which is bound to show up in the next victim!
