“Yes,” said Desmalions.  “To assist his recovery from a long attack of influenza which had kept him in bed all the winter, Mr. Mornington, by his doctor’s orders, used to give himself injections of glycero-phosphate of soda.  He must have omitted the necessary precautions on the last occasion when he did so, for the wound was poisoned, inflammation set in with lightning rapidity, and Mr. Mornington was dead in a few hours.”

The Prefect of Police turned to the solicitor and asked: 

“Have I summed up the facts correctly, Maitre Lepertuis?”

“Absolutely, Monsieur le Prefet.”

M. Desmalions continued: 

“The next morning, Maitre Lepertuis called here and, for reasons which you will understand when you have heard the document read, showed me Cosmo Mornington’s will, which had been placed in his hands.”

While the Prefect was looking through the papers, Maitre Lepertuis added: 

“I may be allowed to say that I saw my client only once before I was summoned to his death-bed; and that was on the day when he sent for me to come to his room in the hotel to hand me the will which he had just made.  This was at the beginning of his influenza.  In the course of conversation he told me that he had been making some inquiries with a view to tracing his mother’s family, and that he intended to pursue these inquiries seriously after his recovery.  Circumstances, as it turned out, prevented his fulfilling his purpose.”

Meanwhile, the Prefect of Police had taken from among the documents an open envelope containing two sheets of paper.  He unfolded the larger of the two and said: 

“This is the will.  I will ask you to listen attentively while I read it and also the document attached to it.”

The others settled themselves in their chairs; and the Prefect read out: 

“The last will and testament of me, Cosmo Mornington, eldest son of Hubert Mornington and Ermeline Roussel, his wife, a naturalized citizen of the United States of America.  I give and bequeath to my adopted country three fourths of my estate, to be employed on works of charity in accordance with the instructions, written in my hand, which Maitre Lepertuis will be good enough to forward to the Ambassador of the United States.  The remainder of my property, to the value of about one hundred million francs, consisting of deposits in various Paris and London banks, a list of which is in the keeping of Maitre Lepertuis, I give and bequeath, in memory of my dear mother, to her favourite sister Elizabeth Roussel or her direct heirs; or, in default of Elizabeth and her heirs, to her second sister Armande Roussel or her direct heirs; or, in default of both sisters and their heirs, to their cousin Victor Roussel or his direct heirs.
