"If I were not, I should not be here."

"I will put my question differently. I trust you will not consider its repetition offensive. Have you an extensive experience in dealing with gunshot wounds?"

Saxham said roughly:

"I have experience to a certain extent. I will go no further than to say so. I am not undergoing examination as to my professional capabilities that I am aware of, and if you doubt them you are perfectly at liberty to seek medical advice elsewhere."

"My good sir, I have been elsewhere, and the other doctor, when he learned the purport of my visit, relished it as little as your principal is likely to do. With the imminent prospect of a siege before us, we are making ..." The speaker, slipping one hand behind him, moved a step backwards and nearer to the room-door. "As I said, sir, with the imminent prospect of a siege before us, we are making a house-to-house requisition.... Ah, I thought as much!"

The door-knob had been quietly turned, the door suddenly pulled open, bringing with it Koets, the Dutch dispensary-attendant, whose large red ear had been glued to the outer keyhole.

"Your Dutch factotum has been listening. Pick yourself off the mat, Jan, and take yourself out of earshot." The stranger whistled the beginning of a pleasant little tune, with a flavour of Savoy Opera about it.

"Ik heb not the neem of Jan," snarled the detected Koets, retiring in disorder.

The whistler left off in the middle of a deftly-executed embellishment to say: "Unfortunate; because I don't know the Dutch word for spy." The keen hazel eyes and the haggard blue ones met, and there was the faint semblance of a smile on the grim mouth of the Dop Doctor. Keeping the door open, the visitor went on:

"I have some notes here—entries copied from the Railway freight-books. Three weeks ago twenty carboys of carbolic acid, with a considerable consignment of other antiseptics, surgical necessaries, drugs, and so forth were delivered to Dr. Williams' order at this address. Frankly, as the officer commanding Her Majesty's troops on this border, I am here to make a sequestration of the things I have mentioned, with all other medical and surgical requisites stored upon the premises, that are likely to be of use to us at the Hospital. In the name of the Imperial Government."
