“Then could Evangeline have been a child of Lady Madeley—unacknowledged, of course?”

“No, that can’t be true either.”

“Why not?”

“Evangeline is left at Lady Stableford’s House on a certain date—within ten days of the date of the marriage of Lord and Lady Madeley. The child that was left was less than ten days old. That much the doctors can swear to. I’ve seen the case book of the man Lady Stableford called in. The child must have been born within a margin of two days on either side of the date of the wedding. Lord Madeley dined with his fiancée at the Langham Hotel the night before the wedding. Obviously a woman could not have been dining out within twenty-four hours of having had a child. The day before that she came to town from Cornwall. After the wedding they went to Paris. The child could not have been born on the wedding day. The day after they dined at the Embassy in Paris. The next day they went on further south. No, Lady Madeley could not have given birth to a child at that time.

“Besides, Marston, the hundred years in the secret trust was to run from 18th August, 1881. That was the date of the wedding day, and that was stated to be the date of the birth of the child originally offered to Lady Stableford, and in all probability that was the child she did adopt. The secret trust was for the benefit of Evangeline, of that I am certain. By the way, I suppose your firm aren’t Lady Stableford’s solicitors by any chance?”

“As it happens we are—or at any rate were. We still have a lot of her papers. She was one of Sir John’s old original clients. Sir John acted for her when she was negotiating for the adoption of that child which you say is Evangeline.”

“Did you make her will?”

“Sir John did.”

“Why didn’t you tell me that?”

“How was I to know there was any connection?”
