“That is also quite modern,” said the lady.
“Done about the same time as the bell-rope?” remarked Holmes.
“Yes, there were several little changes carried out about that time.”
“They seem to have been of a most interesting character—dummy bell-ropes, and ventilators which do not ventilate. With your permission, Miss Stoner, we shall now carry our researches into the inner apartment.”
Dr. Grimesby Roylott’s chamber was larger than that of his step-daughter, but was as plainly furnished. A camp-bed, a small wooden shelf full of books, mostly of a technical character, an armchair beside the bed, a plain wooden chair against the wall, a round table, and a large iron safe were the principal things which met the eye. Holmes walked slowly round and examined each and all of them with the keenest interest.
“What’s in here?” he asked, tapping the safe.
“My stepfather’s business papers.”
“Oh! you have seen inside, then?”
“Only once, some years ago. I remember that it was full of papers.”
“There isn’t a cat in it, for example?”
“No. What a strange idea!”
“Well, look at this!” He took up a small saucer of milk which stood on the top of it.
“No; we don’t keep a cat. But there is a cheetah and a baboon.”
“Ah, yes, of course! Well, a cheetah is just a big cat, and yet a saucer of milk does not go very far in satisfying its wants, I daresay. There is one point which I should wish to determine.” He squatted down in front of the wooden chair and examined the seat of it with the greatest attention.
