The fat adventurer hopped hurriedly across the threshold, Kirkwood following. The woman shut the door, and turned with back to it, nodding significantly at Kirkwood as her eyes met Calendar's.

"Well, well?" snapped the latter impatiently, turning to the young man.

But Kirkwood was thinking quickly. For the present he contented himself with a deliberate statement of fact: "Miss Calendar has disappeared." It gave him an instant's time ... "There's something damned fishy!" he told himself. "These two are playing at cross-purposes. Calendar's no fool; he's evidently a crook, to boot. As for the woman, she's had her eyes open for a number of years. The main thing's Dorothy. She didn't vanish of her own initiative. And Mrs. Hallam knows, or suspects, more than she's going to tell. I don't think she wants Dorothy found. Calendar does. So do I. Ergo: I'm for Calendar."

"Disappeared?" Calendar was barking at him. "How? When? Where?"

"Within ten minutes," said Kirkwood. "Here, let's get it straight.... With her permission I brought her here in a four-wheeler." He was carefully suppressing all mention of Frognall Street, and in Calendar's glance read approval of the elision. "She didn't want to get out, unless you were here. I asked for you. The maid showed me up-stairs. I left your daughter in the cab—and by the way, I hadn't paid the driver. That's funny, too! Perhaps six or seven minutes after I came in Mrs. Hallam found out that Miss Calendar was with me and wanted to ask her in. When we got to the door—no cab. There you have it all."

"Thanks—it's plenty," said Calendar dryly. He bent his head in thought for an instant, then looked up and fixed Mrs. Hallam with an unprejudiced eye, "I say!" he demanded explosively. "There wasn't any one here that knew—eh?"

Her fine eyes wavered and fell before his; and Kirkwood remarked that her under lip was curiously drawn in.

"I heard a man leave as Mrs. Hallam joined me," he volunteered helpfully, and with a suspicion of malice. "And after that—I paid no attention at the time—it seems to me I did hear a cab in the street—"

"Ow?" interjected Calendar, eying the woman steadfastly and employing an exclamation of combined illumination and inquiry more typically British than anything Kirkwood had yet heard from the man.

For her part, the look she gave Kirkwood was sharp with fury. It was more; it was a mistake, a flaw in her diplomacy; for Calendar intercepted it. Unceremoniously he grasped her bare arm with his fat hand.
