"None whatever!" the Commander-in-Chief replied. "When he left for Windsor he informed them he should be back early, in order to dress for my dinner in the evening. They say he appeared to be in the best of health and spirits, and seemed greatly pleased with the arrangements made for his journey to-day. Lord Laverstock accompanied him from the Castle, and was the last to speak to him at Windsor Station. From the conversation I have had with him by telephone, I gathered that Woller was looking forward to his dinner with us last night. The guard of the train corroborates the fact that he travelled to Paddington. For the reason that the Railway Authorities expected him by the next train, there was no crowd upon the platform to witness his arrival. On alighting he simply called a cab and drove away. After that he vanishes completely."

"There is no way, I suppose, in which we can make further enquiries concerning him?"

"There is nothing so far as I can see. We are doing all that is possible, but our position in the meantime is a most anxious and unpleasant one. Now I shall hasten along to see the Secretary of State for War, and hear what he thinks of the situation. He will doubtless consider it necessary to call an immediate meeting of the Council, when the situation can be discussed in all its bearings."

"Let us hope that he may be heard of before very long," I replied.

So saying I left him and drove home again, feeling sadly upset by the untoward turn events had taken. What could have become of poor Woller? Had he been decoyed into some slum and murdered? A hundred fears for his safety assailed me, each one equally probable and equally cruel.

When I reached my house I found that the letters had arrived, and were spread out upon my study table. Still thinking of Woller, I opened the envelopes and scanned their contents. One was larger than the others, and on opening it I found that it contained a card, upon which the following words were printed:—

"The Countess de Venetza at Home on Wednesday, November the 21st, from nine until eleven o'clock."

In the bottom left-hand corner was the address, "Wiltshire House."

As I stood with the card in my hand, the memory of my first meeting with the Countess came back to me. So rapidly had events moved of late, that it seemed as if a year had elapsed since I had last seen her. I recalled the impression her dark haunting eyes had made upon me, and, discourteous though it may be to say so, I must confess that a shudder passed over me at the recollection. I placed the card upon my mantel-piece, and, for the time being, thought no more about it. There were other and more weighty matters than an invitation from a pretty woman to be considered that day.
