The official looked at them with a puzzled expression.

“I can read the first few lines and these in the middle of the second page, and one or two at the end. Those are as clear as print,” said he, “but the writing in between is very bad, and there are three places where I cannot read it at all.”

“What do you make of that?” said Holmes.

“Well, what do you make of it?”

“That it was written in a train. The good writing represents stations, the bad writing movement, and the very bad writing passing over points. A scientific expert would pronounce at once that this was drawn up on a suburban line, since nowhere save in the immediate vicinity of a great city could there be so quick a succession of points. Granting that his whole journey was occupied in drawing up the will, then the train was an express, only stopping once between Norwood and London Bridge.”
