She nodded, but, when he had shaken hands with the Duchess of Ross and was trying to cleave a passage, Barbara was deep in conversation with a pale, underhung youth; and he felt a second twinge of jealousy. She talked until the music stopped, while Jack fingered his tie and strove vainly to keep out of other people's way.

"You know him, don't you?" Barbara asked, when at last the rapt conversation came to an end. "My cousin, Johnnie Carstairs. He's been out in Rome for the last three years, but now he's being transferred to the Foreign Office."

Jack nodded without speaking and continued to look for standing-room. After his letter it was almost inconceivable that she should not know what he wanted to tell her; yet she light-heartedly abandoned him for a cousin whom she could see at any time, talking as though the fellow were on his way to the scaffold; and their promised moment together was relegated to the end of the evening; and in this hurly-burly it was almost too much to expect that they could find an inch of space or a minute of uninterrupted conversation.

"I can see one chair at the far end, if we can get through to it," he said.

"The music's starting," she answered doubtfully. "We'd better get back, I think."

"No, they're playing the same thing. It's only an encore."

"Oh, then do let me have it with Johnnie! I haven't seen him for such ages. You don't mind?"

She had spied a thinning in the crowd and was half-way to the ball-room door before he had an answer ready. Noting the number of the dance, Jack went downstairs and tried to be philosophical over a cigar; but his nerves were unsteady, and, though there was an endless hour and a half to wait, he had to hurry back every few minutes to make sure that he was not missing the promise of supper with Barbara. It was irritating to be so restless—and doubly irritating to feel that others were noticing it. Jim Loring came into the smoking-room and settled himself for a comfortable talk, only to find that his companion had run away unceremoniously in mid-sentence. These people had no sense of the important; life to them was powder and patches and dance music—less than that, for they stayed up half the night to smoke furtive cigars and ostentatiously shut their ears to the dance music. And Barbara was flitting from one man to another, when their two lives were in the balance.

In one of his wanderings to and from the ball-room Jack found Deryk Lancing, ticket in hand, by the cloak-room.
