"He must have sustained a great emotional shock," said another.
"You are convinced that there was no foul play, gentlemen?" I asked.
They were quite unanimous on the point.
"Did the Grand Duke make any statement at the time of the seizure which would confirm the theory of a heart attack?"
No. He had fallen down unconscious outside the door of his box, and from this unconsciousness he had never recovered. (Depositions of witnesses, medical evidence and other documents are available for the guidance of whoever may care to see them, but, as is well known, the death of the Grand Duke was ascribed to natural causes and it seemed as though my trouble would after all prove to be in vain.) Let us see what happened.
Leaving the hotel, on the night of the Grand Duke's death, I joined the man who was watching the cafe telephone.
There had been a message during the course of the evening, but it had been for a Greek cigarette-maker and it referred to the theft of several bales of Turkish tobacco—useful information, of minor kind, but of little interest to me. I knew that it would be useless to question the man Miguel, although I strongly suspected him of being a member of "The Scorpion's" organization. Any patron of the establishment enjoyed the privilege of receiving private telephone calls at the cafe on payment of a small fee.
A man of less experience in obscure criminology might now have assumed that he had been misled by a series of striking coincidences. Remember, there was not a shadow of doubt in the minds of the medical experts that the Grand Duke had died from syncope. His own professional advisor had sent written testimony to show that there was hereditary heart trouble, although not of a character calculated to lead to a fatal termination except under extraordinary circumstances. His own Government, which had every reason to suspect that the Grand Duke's assassination might be attempted, was satisfied. Eh bien! I was not.
I cross-examined the manager of the Theatre Coquerico. He admitted that Mlle. Zara el-Khala had been a mystery throughout her engagement. Neither he nor anyone else connected with the house had ever entered her dressing-room or held any conversation with her, whatever, except the stage-manager and the musical director. These had spoken to her about her music and about lighting and other stage effects. She spoke perfect French.
Such a state of affairs was almost incredible, but was explained by the fact that the dancer, at a most modest salary, had doubled the takings of the theatre in a few days and had attracted capacity business throughout the remainder of her engagement. She had written from Marseilles, enclosing press notices and other usual matter and had been booked direct for one week. She had remained for two months, and might have remained for ever, the poor manager assured me, at five times the salary!
