In a book anthologizing the short stories by LMM, there is a story called "The Dream Child" in which pretends to be a young husband using the most elegant and Victorian rhetoric. He and his wife had a small boy who died and his wife is haunted to the point of destroying herself to "join" him. At the last minute when she is nearly crazy, a small boat washes up on the beach where the lost boy had drowned and in the boat is another little boy, the same age. All is saved. The story is remarkably secular with a wise old doctor instead of a pastor. The explanation is that a wicked woman had put the boy adrift. There were no bulrushes mentioned.
