The messenger left the room.

M. Desmalions stood in front of his desk, without moving. For the second time Don Luis met his eyes; and a feeling of perturbation came over him. What was happening?

With a sharp movement the Prefect of Police opened the envelope which he held in his hand, unfolded the letter and began to read it.

The others watched his every gesture, watched the least change of expression on his face. Were Perenna's predictions about to be fulfilled? Was a fifth heir putting in his claim?

The moment he had read the first lines, M. Desmalions looked up and, addressing Don Luis, murmured:

"You were right, Monsieur. This is a claim."

"On whose part, Monsieur le Préfet?" Don Luis could not help asking.

M. Desmalions did not reply. He finished reading the letter. Then he read it again, with the attention of a man weighing every word. Lastly, he read aloud:

"MONSIEUR LE PRÉFET:

"A chance correspondence has revealed to me the existence of an unknown heir of the Roussel family. It was only to-day that I was able to procure the documents necessary for identifying this heir; and, owing to unforeseen obstacles, it is only at the last moment that I am able to send them to you by the person whom they concern. Respecting a secret which is not mine and wishing, as a woman, to remain outside a business in which I have been only accidentally involved, I beg you, Monsieur le Préfet, to excuse me if I do not feel called upon to sign my name to this letter."
