“We have already offered to assist you to discover the whereabouts of Mrs Holford,” the elder man pointed out politely.

“Then inquire of this man Kirk, or Seymour, as he calls himself, in Whitehall Court,” I said. “He can tell you where she is—if he chooses.”

“You suspect him of having a hand in her disappearance? Why?” inquired the other detective officer.

I related clearly and succinctly the facts upon which my belief was based and of the description given of my wife’s companion by the hotel-manager in Florence.

The officer slowly shook his head.

“That’s scarcely conclusive, is it? The description is but a vague one, after all.”

“Well,” I said bitterly as I rose, “if you refuse to assist me, I must, I suppose, seek redress elsewhere. May I see the Commissioner myself?”

“You can make formal application, if you like. But I don’t expect he will see you. He has already fully considered the matter.” And that was all the satisfaction accorded me.

“Then I’ll do something!” I cried. “I’ll get a question asked in the House. It’s a scandal that, with Professor Greer killed in his own home, you refuse to bestir yourselves. After all, it seems quite true, as has been recently alleged, that the police are nowadays so fully occupied in regulating the speed of motor-cars that they have no time for the investigation of crime.”

I noticed that at my threat to have a question asked in the House, one of the officers pulled a rather wry face. The Metropolitan Police were not fond, I knew, of questions being put about them. I chanced to know rather intimately a member for a country division, though to get the question put would necessitate my explaining the whole affair.
