But a careful murderer does not leave things to chance.

The murderer could not have left by the route that he took to get here.

The murderer, however, had left half an hour earlier.

The murderer left by the door, locking it and taking the key with him.

If a murderer leaves a body out in the open the first time, they'll do it the second, then the third.

But the woman's murderer left no mental scent around the corpse.

At the same time, there's a good chance that the murderer left the clock alone.

Again the murderer had left trace of a possible weapon.

Besides, there is no possible way in which a murderer could have left the room.

The murderer had simply killed and left her, not the way of footpads living wild.
