"I think I must go now," she announced abruptly, and rose, got past him somehow, and made blindly for the door. Then there was the dim vista of the long hall stretching before her, like a path of escape, and she fled its length, and down that of the staircase. Then out at the street-door, and into the chill of the cold December noonday.

When she had vanished, Francis Ronald stood a moment with eyes fixed in the direction she had taken. Then, abruptly, he seized the telephone that stood upon the table beside him, switched it to connect with the basement region, and called for Mrs. Slawson.

"This is Mr. Ronald speaking. Is Martha there?"

"Yes, sir. Please hold the wire, and I'll call her."

"Be quick!"

"Yes, sir!"

A second, and Martha's voice repeated his name. "Mr. Ronald, this is
Martha!"

"Good! I want you to put on your things at once, and follow Miss Lang," he directed briefly. "I do not think she's sick, but as she was talking to me, I noticed she grew suddenly quite pale, and seemed troubled and anxious. Waste no time! Go at once!"

The only answer was a sharp click over the wire, as Mrs. Slawson snapped the receiver into its crotch.

But though Claire was not five minutes in advance of her, Martha was unable to make up the distance between them, and by the time she had mounted the stairs leading to the Elevated, and stood panting for breath on the platform, the train she had hoped to catch was to be seen disappearing around the curve at Fifty-third Street.
