Murder in the 1st Person Singular

It's a chilly, rainy night at the Stonebridge School for Proper Young Ladies as the English teacher, the home ec. teacher, the athletic coach, the butler, the head of the alumnae and a mafia hit man break into the dean's study to kill him. The trouble is they each find him already very dead with a noose around his neck, two suicide notes in his pocket and a Japanese ceremonial dagger in his back. Now it's Detective Bliss' job to find out who did what, with what, when, and why. Meanwhile, the suspects are trying to bump each other off. And who is that mysterious man in the trench coat, and what about the rapidly defrosting moose on the kitchen table?
