'Has he been since?'

'No, sir, but—I was coming in a night or two after, sir, and I saw him standing on the opposite side of the way, looking at the house. He hadn't called, however, and he didn't again.'

Egremont bent his eyes on the ground, and delayed a moment before asking:

'Who else has been?'

'A gentleman; I don't know who it was. The servant went to the door. He said he only wished to know if you were in town or not. He wouldn't leave a name.'

Egremont's face changed to annoyance. He did not care to pursue the subject.

'Let me have something to eat, please,' he said.

The landlady having withdrawn, he at once sat down to his desk and wrote a note. It was to Grail, and ran in substance:

'I am just back from the Continent. Am I right in thinking that it is you who have called here twice in my absence? If so, your second call was at a time when I hoped you were out of London. Do let me see you as soon as possible. Of course you received my letter from Jersey? Shall I come to you, or will you come here? I will stay in to-night. I send this by a messenger, as I wish you to receive it immediately.'

The landlady had a son at home, a lad of sixteen. Having discovered that the boy's services were available, Egremont gave him directions. He was to take a cab and drive to the library in Brook Street. If he should not find Grail there, he was to proceed to Walnut Tree Walk. If Grail would come back with him, so much the better.
