"Why, exactly?"

"For several reasons. One is that I shall be able to purchase some local Cornish maps and a directory or two, which I need, and found no opportunity of procuring in London. But that is not all. Here we are in the very centre of air matters, as far as the Atlantic is concerned. The place is still seething with excitement. Nothing else but the piracies is spoken of. The town is packed with correspondents of the principal European newspapers. It is in a ferment. I much wish to go about with my ears open for an hour or two. I do think, Sir John, that it would be unwise to neglect this opportunity, for you as well as myself. There is no knowing what we may pick up."

"You're certain about my disguise?"

"Perfectly certain. You will not, of course, enter into long conversations with anyone who knows you well, as your voice would betray you. Otherwise you may rest secure."

"Yes, that's the weak point," I replied. "I've always heard that, however perfectly a man may be disguised, you cannot disguise his voice."

He rolled a cigarette with the quick snatching movement of his fingers that always struck me as a miracle of dexterity.

"It is not true," he remarked. "I have invented five methods, three mechanical and two medical or chemical, whichever you like to call them. When we have leisure I will show you. But there is no need for anything of the sort in your case. It will give you confidence, Sir John, to test the completeness of your new appearance. If you will go to the Royal Hotel and lunch there—keeping awake to hear the general talk—I will join you about three."

"Very well," I replied, though with some reluctance, "and the car?"

"Mr. Thumbwood has been with you at the 'Royal,' and he is not disguised. It would be better that he should not approach the hotel. We will put you down a short distance away. I will remain in the car and direct Thumbwood where to go."

Nothing escaped this little man! He seemed to foresee and provide for everything, and when I alighted five minutes afterwards, some two hundred yards from the hotel, I felt fairly secure in my new character as Mr. Johns, the don of Christ Church, Oxford.
