“I’ve heard of your methods before now, Mr. Holmes,” said he tartly. “You are ready enough to use all the information that the police can lay at your disposal, and then you try to finish the case yourself and bring discredit on them.”

“On the contrary,” said Holmes, “out of my last fifty-three cases my name has only appeared in four, and the police have had all the credit in forty-nine. I don’t blame you for not knowing this, for you are young and inexperienced, but if you wish to get on in your new duties you will work with me and not against me.”

“I’d be very glad of a hint or two,” said the detective, changing his manner. “I’ve certainly had no credit from the case so far.”

“What steps have you taken?”

“Tangey, the commissionaire, has been shadowed. He left the Guards with a good character, and we can find nothing against him. His wife is a bad lot, though. I fancy she knows more about this than appears.”

“Have you shadowed her?”

“We have set one of our women on to her. Mrs. Tangey drinks, and our woman has been with her twice when she was well on, but she could get nothing out of her.”

“I understand that they have had brokers in the house?”

“Yes, but they were paid off.”

“Where did the money come from?”

“That was all right. His pension was due. They have not shown any sign of being in funds.”

“What explanation did she give of having answered the bell when Mr. Phelps rang for the coffee?”

“She said that her husband was very tired and she wished to relieve him.”

“Well, certainly that would agree with his being found a little later asleep in his chair. There is nothing against them then but the woman’s character. Did you ask her why she hurried away that night? Her haste attracted the attention of the police constable.”

“She was later than usual and wanted to get home.”

“Did you point out to her that you and Mr. Phelps, who started at least twenty minutes after her, got home before her?”

“She explains that by the difference between a ’bus and a hansom.”

“Did she make it clear why, on reaching her house, she ran into the back kitchen?”

“Because she had the money there with which to pay off the brokers.”

“She has at least an answer for everything. Did you ask her whether in leaving she met anyone or saw anyone loitering about Charles Street?”

“She saw no one but the constable.”

“Well, you seem to have cross-examined her pretty thoroughly. What else have you done?”

“The clerk Gorot has been shadowed all these nine weeks, but without result. We can show nothing against him.”

“Anything else?”

“Well, we have nothing else to go upon -no evidence of any kind.”

“Have you formed any theory about how that bell rang?”

“Well, I must confess that it beats me. It was a cool hand, whoever it was, to go and give the alarm like that.”

“Yes, it was a queer thing to do. Many thanks to you for what you have told me. If I can put the man into your hands you shall hear from me. Come along, Watson.”

“Where are we going to now?” I asked as we left the office.

“We are now going to interview Lord Holdhurst, the cabinet minister and future premier of England.”
