“Yes, that’s what I meant. You don’t think it was the reason he certainly wanted us to believe, then—that he was bored with her?”

“I know it wasn’t,” the inspector returned shrewdly. “He’s a chivalrous young gentleman as far as the ladies are concerned, is Mr. Woodthorpe, and he’d never break with an old flame who was still desperately in love with him merely because he’d got bored with her. There was some much more powerful reason than that behind it.”

“Ah!” said Roger. “I was right; you are a psychologist, after all, Inspector. And what do you think of this reason that friend Colin is so industriously hiding from us?”

“I think,” the inspector said slowly, “that it would go a long way toward clearing up the case for us, if we knew it.”

Roger whistled. “As important as all that, eh? I must say, I hadn’t arrived at that conclusion myself. And have you got any inkling as to its nature?”

“Well—!” The inspector took a sup of whisky and wiped his moustache again with some deliberation. “Well, the most likely thing would be another girl, wouldn’t it?”

“You mean, he’d fallen seriously in love elsewhere?”

And wanted to get engaged to her,” the inspector amplified. “Was engaged to her secretly, if you like. That’s the only thing I can see important enough to make him resolve to break with Mrs. Vane at all costs.”

Roger nodded slowly. “Yes, I think you’re right.—But I’m blessed if I see how knowing it for certain is going to clear up the case for you?”

“Can’t you, sir?” the inspector replied cautiously. “Well perhaps it’s only a whim of mine, so we’ll say no more about it for the time being.”
