The Charing Cross Mystery by J.S. Fletcher

The head-waiter in the restaurant to which Hetherwick and Rhona repaired every Sunday immediately upon her arrival now knew these two well by sight, and forming his own conclusions about them, always reserved for them a table in a quiet and secluded corner. Hither they now proceeded, and had scarcely taken their accustomed seats before Rhona plunged into her story.

"I expect you want to know what it's all about, so I won't keep you waiting," she said. "It was on Friday -- Friday morning -- that it happened, and I half thought of writing to you about it that evening. Then I thought it best to tell you personally to-day -- besides, I should have had to write an awfully long letter. There are things to explain; I'd better explain them first. Our arrangements down there at Riversreade, for instance. They're like this: Lady Riversreade and I always breakfast together at the Court, about nine o'clock. At ten we go across the grounds to the Home. There we have a sort of formal office -- two rooms, one of which, the first opening from the hall, I have, the other, opening out of it, is Lady Riversreade's private sanctum. In the hall itself we have an ex-army man, Mitchell, as hall-porter, to attend to the door and so on. All the morning we are busy with letters, accounts, reports of the staff, and that sort of thing. We have lunch at the Home, and we're generally busy until four or five o'clock. Got all that?"
