"What the devil have I stumbled upon, anyhow?" muttered Wren, as he hastily drew back from the window. "Here's a connection between Slosson, the lady, and Macgowan—but what's the connection? Damned if I can see any. A fine fool, I am! If I'd trusted Mrs. Armstrong enough to—"

He started, and a slow smile came to his lips. Dorothy Armstrong! Somehow, Slosson was connected with the private trouble of the Armstrongs; just how, he did not know. But Dorothy would know. Here was the weapon laid ready to his hand, could he but use it!

"By the gods, I'll use it, too!" he exclaimed to himself, flaming at the thought. "Reese has gone West. I'll beat it to Evansville and make a clean breast of the whole thing to Dorothy; got to do that, now. Whatever the reason she left Reese, this business will throw some light on it, I'll bet. How did Slosson come to know Mrs. Fowler, anyhow? Why, Macgowan put him next, that's all. And it was Lorenz, Mac's friend, who introduced me—well, I'm getting a line on this thing, right enough!"

The apartment door opened and closed again.

When Mrs. Fowler stepped into the room, Jimmy Wren was puffing away at a fresh cigar and making some notes in a memorandum book, too absorbed to hear her entry. She shot one swift glance at the desk, then came forward. Wren was on his feet instantly, his face beaming with surprise and delight.

"Hello—I didn't hear you come in! May I stop and talk to you for a moment?"

"My dear boy, I'm delighted!" she greeted him warmly. "Why didn't you call up and I'd have been here?"

"I came in a rush, as usual," and Jimmy grinned as he helped Mrs. Fowler doff her wraps, and handed them to the maid. "You see, I'm leaving town to-night for a day or so, and I wanted to get a last glimpse of you before going."

"Mercy! You're not starting for the North Pole?" Smiling, the lady seated herself among the pillows of the window-seat, and accepted the cigarette which Jimmy procured for her. "Thank you. What's this sudden trip about? More business?"

"Nope," responded Jimmy Wren. "An aunt of mine is dying in Chicago, and I'll have to run out there and do the decent thing. Haven't seen the old lady for uncounted years, but that doesn't matter. Too bad I didn't get the wire a few hours earlier. I might have gone with Reese. He's off this afternoon—gone to Chicago to look into some bond issue they want him to take over."
