"You are quite mistaken," she said thoughtfully. "George Calendar has not been here this night."

He wondered that she did not seem to resent his imputation. "I think not—"

"Listen!" she cried, raising a warning hand; and relaxing her vigilant attitude, moved forward once more, to peer down toward the Embankment.

A cab had cut in from that direction and was bearing down upon them with a brisk rumble of hoofs. As it approached, Kirkwood's heart, that had lightened, was weighed upon again by disappointment. It was no four-wheeler, but a hansom, and the open wings of the apron, disclosing a white triangle of linen surmounted by a glowing spot of fire, betrayed the sex of the fare too plainly to allow of further hope that it might be the girl returning.

At the door, the cab pulled up sharply and a man tumbled hastily out upon the sidewalk.

"Here!" he cried throatily, tossing the cabby his fare, and turned toward the pair upon the doorstep, evidently surmising that something was amiss. For he was Calendar in proper person, and a sight to upset in a twinkling Kirkwood's ingeniously builded castle of suspicion.

"Mrs. Hallam!" he cried, out of breath. "'S my daughter here?" And then, catching sight of Kirkwood's countenance: "Why, hello, Kirkwood!" he saluted him with a dubious air.

The woman interrupted hastily. "Please come in, Mr. Calendar. This gentleman has been inquiring for you, with an astonishing tale about your daughter."

"Dorothy!" Calendar's moon-like visage was momentarily divested of any trace of color. "What of her?"

"You had better come in," advised Mrs. Hallam brusquely.
