Blaythwayt came up at that moment, wiping his hands on a stained handkerchief. He was still round-eyed with interest; but otherwise, except for an excusable excitement, he was remarkably self-possessed. "An Extraordinary Experience!" he said. "Of course, one's very sorry for all those poor wretches; but still..." He broke off with a shrug, as though to imply that the scientific mind transcended such mundane considerations. "I ought to drop in at the Yard," Teal said with a sigh. "You've got an advantage over me, Captain Arden--you're not a regular and you don't have to bother so much about routine." He yawned. "Lordy! I seem to average about ten minutes' sleep per night these days," he complained somewhat paradoxically. "You'll average less for the next seventy hours or so!" Storm told him. "I'll come with you--I might find the Commissioner in." Joe Blaythwayt was skipping eagerly in front of them. "D'you think I could come too?" he pleaded wistfully. "I've never had a chance to see inside Scotland Yard, and after what's happened to-night it seems as if my Luck Is In--I don't mean to be callous," he excused himself incoherently. "I'm sorry, as I said, but----" Teal shook an admonishing finger at him. "Joe, you go home to bed," he commanded sternly. "You're a bloodthirsty little man, and I think you've had all the horrors that's good for you to-night." "Oh, let him come," Storm interrupted wearily. "What the devil does it matter, anyway?" They found a taxi in Trafalgar Square and piled in. Joe Blaythwayt, still clasping his umbrella, which somehow he had managed to retain throughout the proceedings, was all agog with anticipation. Decidedly, one would have thought, he regarded it as His Evening. Storm was less cheerful. "The hell of it is that I feel responsible," he explained bitterly. "I deliberately let the Triangle get away, and now he's made to-night's mess. Selfishness--or quixoticism, if you like--I don't know. Listen, Teal, and I'll tell you something! I've known the Triangle for days, but I wasn't going to show him up in the usual way, as I told the Inquiry, for the reason you know." "You know the Triangle?" broke in Teal incredulously. "I thought that was a bluff you put up for the Board." "Yes, I know him. I'll tell you what my idea was. I'm a fool, maybe, but because he's my father I didn't want any publicity. And by the same token, I couldn't very well kill him myself. So what I intended to do was collect so much evidence that I could go to him and lay it before him so definitely he'd see the only alternative to hanging was--suicide. I know what his choice'd have been." "Have you got that evidence now?" "No," said Storm bitterly, and was silent all the rest of the way to Cannon Row.
