It was so utterly obvious to the man behind the pillar, that for a while he watched them with the same disinterested feeling that he would have watched a play.

"She's telling him what a rotten life she's had," he reflected, cynically. "Her husband doesn't understand her. Fordingham answers the obvious cue with a soulful look. If only he had been the husband in question, there would have been no misunderstanding. Perhaps not. Only a broken heart, my Colt, that's all."

He looked up as François stopped in front of his table.

"She doesn't know I'm here, does she?" asked Hugh, quietly.

"No, M'sieur." The head-waiter glanced a little sadly at the two heads so close together.

Hugh took a piece of paper from his pocket, and scribbled a few words on it in pencil.

"I don't want her to know—at least, not yet. Would you ask the orchestra to play that?" He handed the slip across the table. "It's important." And then, "Wait, François; I want to find out where she goes to after dinner. It's too late now for a theatre, and I expect she's staying at an hotel. Can you do that for me?"

The head-waiter nodded in silence, and moved away. Very few men would have asked him to do such a thing; he would have done it for still fewer. But this was an exception, and tragedy is never far off when the Fordinghams of this world dine with youngsters who have run away from their husbands.

Hugh, with an eagerness which almost suffocated him, waited for the first bars of the waltz he had asked the orchestra to play. The last time he had heard it, he had been dining at the Milan with Doris. It was their favourite waltz; on every programme they had made a point of dancing it together. Would she remember? Would it break through the wretched wall of misunderstanding, and carry her back to the days when it was just they two, and there was nothing else that mattered in the whole wide world?

The haunting melody stole gently through the room, and, with his heart pounding madly, Hugh Lethbridge watched his wife. At the very first note she sat up abruptly, and with a grim triumph Hugh saw the look of sudden surprise on her companion's face. Then, very slowly, she turned and stared at their usual table. Her lips were parted, and to the man who watched so eagerly it seemed as if she were breathing a little quickly. Almost he fancied he could see a look of dawning wonder in her eyes, like a child awakening in a strange room.
