‘I can stay,’ I said.

‘You?—Alone?’

He eyed me doubtingly,—evidently not altogether relishing the proposition.

‘Why not? You might send the first person you meet,—policeman, cabman, or whoever it is—to keep me company. It seems a pity now that we dismissed that cab.’

‘Yes, it does seem a pity.’ Sydney was biting his lip. ‘Confound that fellow! how fast he moves.’

Mr Holt was already nearing the end of the road.

‘If you think it necessary, by all means follow to see where he goes,—you are sure to meet somebody whom you will be able to send before you have gone very far.’

‘I suppose I shall.—You won’t mind being left alone?’

‘Why should I?—I’m not a child.’

Mr Holt, reaching the corner, turned it, and vanished out of sight. Sydney gave an exclamation of impatience.
