Not a lackey, perhaps, but a sort of confidential retainer.

That will be best, Master Rupert, in every way." Rupert was silent for a moment.
"Well, Hugh, perhaps that would be best; but you must remember that whatever we are before others, we are always friends when we are alone." "Very well," Hugh said, "that is understood; but you know that alone or before others, I shall always be your faithful servant." "What can I make you, sir ?" the tailor asked, as the lads entered his shop.
Master Haliford was a small man; neat in his dress; a little fussy in manner.

He was very upright, and seemed to look under rather than through the pair of horn spectacles which he wore.

His look changed from affability to doubt as he took a nearer look at his intending customers.
"I need a suit such as a gentleman might wear at court," Rupert said, quietly, "and a walking or ordinary suit for myself; and a suit such as would be worn by a trusted retainer for my friend here." The tailor put his head on one side, and rubbed his chin thoughtfully.
"Have I had the honour of being recommended to you by the honourable gentleman your father ?" he asked.
"No, indeed," Rupert said.

"It was mine host at the Bell, who advised me that I could not do better than come to your shop." "Ah, you are known to him, beyond doubt," John Haliford said, brightening.
"No, indeed," Rupert answered.
