so far,then,the picture is like this. we have a murder with a peculiar voice, and who is unusually agile. we have a murder without motive, a murder that is brutal and horrible even for the worst kind of criminal. how many murderers kill with their own hands, and then push the body, head downwards, up a chimney? and how strong our murderer is! he pushed the body up alone, but it took three or four people to pull it down. and think of those handfuls of long grey hair on the floor. have you ever tried to pull hair out of someone's head? you need to be very strong to do that. you also need to be strong to cut right through someone's neck-with just a razor. and why did the old lady have so money broken bones? because the murderer pushed her body through the open window, and it fell down onto the stones of the yard below.
