“See here, Mr. Trent,” he said, after a few moments. “There are some things I can tell you that may be useful to you. I know your record. You are a smart man, and I like dealing with smart men. I don’t know if I have that detective sized up right, but he strikes me as a mutt. I would answer any questions he had the gumption to ask me—I have done so, in fact—but I don’t feel encouraged to give him any notions of mine without his asking. See?”

Trent nodded. “That is a feeling many people have in the presence of our police,” he said. “It’s the official manner, I suppose. But let me tell you, Murch is anything but what you think. He is one of the shrewdest officers in Europe. He is not very quick with his mind, but he is very sure. And his experience is immense. My forte is imagination, but I assure you in police work experience outweighs it by a great deal.”

“Outweigh nothing!” replied Mr. Bunner crisply. “This is no ordinary case, Mr. Trent. I will tell you one reason why. I believe the old man knew there was something coming to him. Another thing: I believe it was something he thought he couldn’t dodge.”

Trent pulled a crate opposite to Mr. Bunner’s place on the footboard and seated himself. “This sounds like business,” he said. “Tell me your ideas.”

“I say what I do because of the change in the old man’s manner this last few weeks. I dare say you have heard, Mr. Trent, that he was a man who always kept himself well in hand. That was so. I have always considered him the coolest and hardest head in business. That man’s calm was just deadly—I never saw anything to beat it. And I knew Manderson as nobody else did. I was with him in the work he really lived for. I guess I knew him a heap better than his wife did, poor woman. I knew him better than Marlowe could—he never saw Manderson in his office when there was a big thing on. I knew him better than any of his friends.”

“Had he any friends?” interjected Trent.

Mr. Bunner glanced at him sharply. “Somebody has been putting you next, I see that,” he remarked. “No: properly speaking, I should say not. He had many acquaintances among the big men, people he saw, most every day; they would even go yachting or hunting together. But I don’t believe there ever was a man that Manderson opened a corner of his heart to. But what I was going to say was this. Some months ago the old man began to get like I never knew him before—gloomy and sullen, just as if he was everlastingly brooding over something bad, something that he couldn’t fix. This went on without any break; it was the same down town as it was up home, he acted just as if there was something lying heavy on his mind. But it wasn’t until a few weeks back that his self-restraint began to go; and let me tell you this, Mr. Trent”—the American laid his bony claw on the other’s knee—“I’m the only man that knows it. With every one else he would be just morose and dull; but when he was alone with me in his office, or anywhere where we would be working together, if the least little thing went wrong, by George! he would fly off the handle to beat the Dutch. In this library here I have seen him open a letter with something that didn’t just suit him in it, and he would rip around and carry on like an Indian, saying he wished he had the man that wrote it here, he wouldn’t do a thing to him, and so on, till it was just pitiful. I never saw such a change. And here’s another thing. For a week before he died Manderson neglected his work, for the first time in my experience. He wouldn’t answer a letter or a cable, though things looked like going all to pieces over there. I supposed that this anxiety of his, whatever it was, had got on to his nerves till they were worn out. Once I advised him to see a doctor, and he told me to go to hell. But nobody saw this side of him but me. If he was having one of these rages in the library here, for example, and Mrs. Manderson would come into the room, he would be all calm and cold again in an instant.”

“And you put this down to some secret anxiety, a fear that somebody had designs on his life?” asked Trent.

The American nodded.

“I suppose,” Trent resumed, “you had considered the idea of there being something wrong with his mind—a break-down from overstrain, say. That is the first thought that your account suggests to me. Besides, it is what is always happening to your big business men in America, isn’t it? That is the impression one gets from the newspapers.”
