"Ah!" cried Lupin, suddenly. "The same picture!"

"Exactly the same!" I said. "And the date: do you see the date, in red? 15. 4. 2."

"Yes, I see.... And who lives in that room?"

"A lady ... or, rather, a workwoman, for she has to work for her living ... needlework, hardly enough to keep herself and her child."

"What is her name?"

"Louise d'Ernemont.... From what I hear, she is the great-granddaughter of a farmer-general who was guillotined during the Terror."

"Yes, on the same day as André Chénier," said Lupin. "According to the memoirs of the time, this d'Ernemont was supposed to be a very rich man." He raised his head and said, "It's an interesting story.... Why did you wait before telling me?"

"Because this is the 15th of April."

"Well?"
