Animals and their involvement in impossible crimes enjoy a long history, from the works of Edgar Allan Poe and Arthur Conan Doyle all the way up to the Jonathan Creek episode The House of Monkeys. Approximately halfway between these two we have Roman McDougald’s mandrill Geva, resident of your classical American Millionaire’s Household and on hand when said millionaire is found murdered in frankly baffling circumstances: in his office, stabbed in the back, with both doors into the room unlocked. Yes, unlocked. And yet he failed to leave the room while being attacked – the trail of blood he left leads from his desk to one door, then the other, and halfway back again – or raise the alarm in any way before the killer escaped.
