“But why?” asked Murie.

“Well, truth to tell, the reason is very simple,” he answered.  “As we are speaking here in the strictest privacy, I will tell you something which I beg that neither of you will repeat.  If you do it might result in my ruin.”

Murie, Hamilton, and Gabrielle all gave their promise.

“Then it is this,” he said.  “I am head of a group of the leading financial houses in Europe, who, remaining secret, are carrying on business in the guise of an unimportant house in Paris.  The members of the syndicate are all of them men of enormous financial strength, including Baron de Hetzendorf, to whom our friend Hamilton here acts as confidential secretary.  The strictest secrecy is necessary for the success of our great undertakings, which I may add are perfectly honest and legitimate.  Yet never, unless absolutely imperative, do we entrust documents or letters to the post.  Like the house of Rothschild, we have our confidential messengers, and hold frequent meetings, no ‘deal’ being undertaken without we are all of us in full accord.  Monsieur Goslin acts as confidential messenger, and brings me the views of my partners in Paris, Petersburg, and Vienna.  To this careful concealment of our plans, or of the fact that we are ever in touch with one another, is due the huge successes we have made from time to time—­successes which have staggered the Bourses of the Continent and caused amazement in Wall Street.  But being unfortunately afflicted as I am, I naturally cannot travel to meet the others, and, besides, we are compelled always to take fresh and most elaborate precautions in order to conceal the fact that we are in connection with each other.  If that one fact ever leaked out it would at once stultify our endeavours and weaken our position.  Hence, at intervals, two or even three of my partners travel here, and I meet them at night in the little chamber which you, Walter, discovered to-day, and which until the present has never been found, owing to the weird fables I have invented regarding the Whispers.  To Hetzendorf, too, once or twice a year, perhaps, the members pay a secret visit in order to consult the Baron, who, as you perhaps may know, unfortunately enjoys very precarious health.”

“Then meetings of Frohnmeyer, Volkonski, and the rest were held here in secret sometimes?” echoed Hamilton in surprise.

“On certain occasions, when it is absolutely necessary that I should meet them,” answered Sir Henry.  “They stay at the Station Hotel in Perth, coming over to Auchterarder by the last train at night and leaving by the first train in the morning from Crieff Junction.  They never approach the house, for fear that servants or one or other of the guests may recognise them, but go separately along the glen and up the path to the ruins.  When we thus meet, our voices can be heard through the crack in the roof of the chamber in the courtyard above.  On such occasions I take good care that Stewart and his men are sent on a false alarm of poachers to another part of the estate, while I can find my way there myself with my stick,” he laughed.  “The Baron, I believe, acts on the same principle at his chateau in Hungary.”
