He let himself in with his latchkey, and entered the drawing-room; it was vacant. He looked into other rooms; no one was there. He rang, and a servant came.

'Has Mrs. Carnaby been out long?'

She had left, was the reply, at half-past two. Whilst she sat at luncheon a telegram arrived for her, and, soon after, she prepared to go out, saying that she would not return tonight.

Not return tonight? Hugh scarcely restrained an exclamation, and had much ado to utter his next words.

'Did she mention where she was going?'

'No, sir. I took the dressing-bag down to the cab, and the cabman was told to drive to the post-office.'

'Very well. That will do.'

'Shall you dine at home, sir?'

'Dine? No.'

Sibyl gone away for the night? Where could she have gone to? He began to look about for the telegram she had received; it might be lying somewhere, and possibly would explain her departure. In the waste-paper basket he found the torn envelope lying at the top; but the despatch itself was not to be discovered.
