“Well, that’s the funny part of it,” explained the other man. “We get to know the names of the habitués sooner or later, but none of us have ever heard his. He never seems to meet anybody here that he knows, and none of the waiters have ever heard one of his guests address him by name. The maître d’hôtel and I have often talked him over, and wondered who and what he was.”

Smeaton showed his disappointment. “That is unfortunate. Let us see if we can be more successful in another direction. Yesterday afternoon, about three o’clock, this man, whose name we don’t know, drove away from this place in a taxi, accompanied by a lady. My informant tells me she was smartly dressed, and he puts her age at about thirty, or perhaps less.”

The hall-porter indulged in a smile of satisfaction.

“I think I can help you there, Mr Smeaton. I was passing through the palm-court at the time, and saw them go out together. We all know the lady very well. She is here pretty often. Sometimes she comes with a big party, sometimes with a lady friend, sometimes with a gentleman. Her name is Saxton, and she has a flat in Hyde Park Mansions. One of her friends told me she is a widow.”

“What sort of a person is she? How would you class her? She seems to dress well, and is, I suppose, attractive.”

The hall-porter mused a moment before he replied. Like most of his class, he was an expert at social classification.

“Not one of the ‘nobs,’ certainly,” he answered at length, with a smile. “Semi-fashionable, I should say; moves in society with a small ‘s.’ Her friends seem of two sorts, high-class Bohemians—you know the sort I mean,—and rich middle-class who spend money like water.”

“I see,” said Smeaton. “And she lives in Hyde Park Mansions off the Edgware Road, or, to be more correct, Lisson Grove. She is evidently not rich.”

They bade each other a cordial good-day, Smeaton having first expressed his gratitude for the information, and left in the hall-porter’s capacious palm a more substantial proof of his satisfaction.

The next thing to be done was to interview the attractive widow. Before doing so, he looked in at Chesterfield Street, and, as he expected, found Wingate and Sheila together.
