“I didn’t. I didn’t look. But what of it?”

“If you will look out of the window you will see that there is a terrace below which gives on the garden. Above the terrace there is a steel framework which reaches almost to the second floor balconies. In the summer it is covered with straw matting so that people can eat and drink on the terrace, out of the sun. This man obviously climbed up by the framework. It would be easy. I could almost do it myself. He could reach the balconies of all the rooms on this floor of the hotel that way. But can you tell me why he chooses to break into one of the few rooms with both shutters and windows locked?”

“Of course I can’t. I’ve always heard that criminals were fools.”

“You say nothing was stolen. Your suitcase was not even opened. A coincidence that you should return just in time to prevent him.”

“A lucky coincidence. For goodness’ sake, Kopeikin, let’s talk about something else. The man’s escaped. That’s the end of it.”

Kopeikin shook his head. “I’m afraid not, my dear fellow. Does he not seem to you to have been a very curious thief? He behaves like no other hotel thief ever behaved. He breaks in, and through a locked window as well. If you had been in bed, he would certainly have awakened you. He must, therefore, have known beforehand that you were not there. He must also have discovered your room number. Have you anything so obviously valuable that a thief finds it worth his while to make such preparations? No. A curious thief! He carries, too, a pistol weighing at least a kilogramme with which he fires three shots at you.”

“Well?”

Kopeikin bounced angrily out of his chair. “My dear fellow, does it not occur to you that this man was shooting to kill you, and that he came here for no other purpose?”

Graham laughed. “Then all I can say is that he was a pretty bad shot. Now you listen to me carefully, Kopeikin. Have you ever heard the legend about Americans and Englishmen? It persists in every country in the world where English isn’t spoken. The story is that all Americans and Englishmen are millionaires, and that they always leave vast amounts of loose cash about the place. And now, if you don’t mind, I’m going to try to snatch a few hours’ sleep. It was very good of you to come round, Kopeikin, and I’m very grateful, but now …”

“Have you ever,” demanded Kopeikin, “tried firing a heavy pistol in a dark room at a man who’s just come through the door? There’s no direct light from the corridor outside. Merely a glow of light. Have you ever tried? No. You might be able to see the man, but it’s quite another thing to hit him. Under these circumstances even a good shot might miss first time as this man missed. That miss would unnerve him. He does not perhaps know that Englishmen do not usually carry firearms. You may fire back. He fires again, quickly, and clips your hand. You probably cry out with the pain. He probably thinks that he has wounded you seriously. He fires another shot for luck, and goes.”
