We did so, and thereupon that reckless youth spent upon flowers what would have kept me in cigars for a month. Having paid for them and given orders that they should be sent to the Hotel Galaghetti at once, we left the shop. When we stood outside, I had to answer all sorts of questions as to whether I thought she would like them, whether it would not have been better to have chosen more of one sort than another, and whether the scent would not be too strong for a sick-room. After that he felt doubtful whether the shopkeeper would send them in time, and felt half inclined to return in order to impress this fact upon the man. Let it be counted to me for righteousness that I bore with him patiently, remembering my own feeling at a similar stage in my career. When we reached the hotel on our return, we discovered that the patient was somewhat better. She had had a short sleep, and it had refreshed her. My wife was going to sit with her during the evening, and knowing this, I felt that we might go out with clear consciences.

At a quarter to seven we retired to our rooms to dress, and at a quarter past the hour were ready to start. When we reached the hall, we found the Don awaiting us there. He was dressed with the greatest care, and presented a not unhandsome figure. He shook hands cordially with me and bowed to Glenbarth, who had made no sign of offering him his hand. Previous to setting out, I had extorted from that young man his promise that he would behave with courtesy towards the other during the evening.

"You can't expect me to treat the fellow as a friend," he had said in reply, "but I will give you my word that I'll be civil to him—if that's what you want."

And with this assurance I was perforce compelled to be content.

Having taken our places in the gondola which was waiting for us, we set off.

"I had the pleasure of seeing Doctor Nikola this morning," said Martinos, as we turned into the Rio del Consiglio. "He did me the honour of calling upon me."

I gave a start of surprise on hearing this.

"Indeed," I replied. "And at what hour was that?"

"Exactly at eleven o'clock," the Don answered. "I remember the time because I was in the act of going out, and we encountered each other in the hall."

Now it is a singular thing, a coincidence if you like, but it was almost on the stroke of eleven that Miss Trevor had been seized with her mysterious illness. At a quarter past the hour she felt so poorly as to be compelled to retire to her room. Of course there could be no connection between the two affairs, but it was certainly a coincidence of a nature calculated to afford me ample food for reflection. A few moments later the gondola drew up at the steps of the Palace Revecce. Almost at the same instant the door opened and we entered the house. The courtyard had been lighted in preparation for our coming, and, following the man who had admitted us, we ascended the stone staircase to the corridor above. Though not so dismal as when I had last seen it, lighted only by Nikola's lantern, it was still sufficiently awesome to create a decided impression upon the Don.
