“You can take it for granted Sir John never gave away a client in his life. The child’s mother is bound to have known. I expect that other person was the mother.

“Still, after all, Yardley,” said the barrister, as he helped himself to another cigarette from his case, “you see, if it were merely the providing for the welfare of a certain person, there are hundreds of ways in which this could have been done without exciting any suspicion at all. Sir John was a clever lawyer, and knew of those ways. The secret trust was so unnecessary. Therefore, though I am still inclined to think my guess correct, I’m certain that if it be correct, there is a lot more to come out. You see, it is quite possible no provision will ever be claimed under the trust—which makes one doubt the daughter idea. What we know or can guess won’t properly explain everything. Yardley, you must find out Mrs. Garnett and who she is.”

“Can’t you set me something easier to do? Working with you somehow always seems to involve these forlorn hopes, wild-goose sort of hunts. How am I to find the woman?”

“God knows, Yardley; I don’t. I think the most likely way would be to trace the birth of Miss Stableford.”

“But we’ve tried that, and failed.”

“I know; but we’ve only tried England. I’ve never been in such a position myself, and perhaps I don’t know, but it’s always a standing mystery to me, why the illegitimate child of a woman who wants to cover up its birth is ever born in England. A few pounds take you over to France, where not a soul knows you. The mother can call herself Mrs. anybody, and register the child as the child of any father or a mythical father, if you like. The fraud couldn’t possibly come out till afterwards, when the mother is safe back in England. I’ve never looked it up, but I doubt if they would extradite for such an offence. It’s forgery here by Act of Parliament, but I don’t suppose it is in France.”

“You might say the same of any country in Europe?”

“Yes, I agree; but don’t forget the child was only ten days old when it was left with Lady Stableford. The baby was already born, for her sex was disclosed when the first letter was written to Lady Stableford. Between the date at which the lady disclosed her name and address and her finding of the child, there was no time for the infant to have been brought from any great distance. The baby was probably born in France.”

“Do you think it’s worth while going to France and making inquiries there?”

“Hardly; for the odds are 20,000 to one against the birth being registered in the correct or any genuine name. Nor do we know what name to look for. Obviously it couldn’t be Stableford.”
