"Quite determined," they replied together. Then the tallest added, "We much regret it, but our decision is irrevocable."

Ten minutes later they had left the hotel in a huff, and I found myself seated upon the horns of a serious dilemma. What would my position be if Nikola's presence should exercise a bad effect upon the patient, or if he should decline to render us assistance? In that case I should have offended the best doctors in Venice, and should in all probability have killed her. It was a nice position to be placed in. One thing, however, was as certain as anything could be, and that was the fact that there was no time to lose. My wife was seriously alarmed when I informed her of my decision, but both Glenbarth and I felt that we were acting for the best, and the Dean sided with us.

"Since you deem it necessary, go in search of Doctor Nikola at once," said my wife, when the latter had left us. "Implore him to come without delay; in another hour it may be too late." Then in a heart-broken whisper she added, "She is growing weaker every moment. Oh, Dick, Heaven grant that we are not acting wrongly, and that he may be able to save her."

"I feel convinced that we are doing right," I answered. "And now I will go in search of Nikola, and if possible bring him back with me."

"God grant you may be successful in your search," said Glenbarth, wringing my hand. "If Nikola saves her I will do anything he may ask, and still be grateful to him all the days of my life."

Then I set off upon my errand.


CHAPTER IX

With a heart as heavy as lead I made my way down-stairs, and having chartered a gondola, bade the man take me to the Palace Revecce with all possible haste. Old Galaghetti, who stood upon the steps, nodded vehement approval, and rubbed his hands with delight as he thought of the triumph his great doctor must inevitably achieve. As I left the hotel I looked back at it with a feeling of genuine sorrow. Only a few days before our party had all been so happy together, and now one was stricken down with a mysterious malady that, so far as I could see, was likely to end in her death. Whether the gondolier had been admonished by Galaghetti to make haste, and was anxious to do so in sympathy with my trouble, I cannot say; the fact, however, remains that we accomplished the distance that separated the hotel from the palace in what could have been little more than half the time usually taken. My star was still in the ascendant when we reached the palace, for when I had disembarked at the steps, the old man who did menial service for Nikola, had just opened it and looked out. I inquired whether his master was at home, and, if so, whether I could see him? He evidently realized that my Italian was of the most rudimentary description, for it was necessary for me to repeat my question three or four times before he could comprehend my meaning. When at last he did so, he pointed up the stairs to signify that Nikola was at home, and also that, if I desired to see him, I had better go in search of him. I immediately did so, and hastened up the stairs to the room I have already described, and of which I entertained such ghastly recollections. I knocked upon the door, and a well-known voice bade me in English to "come in." I was in too great a haste to fulfil my mission to observe at the time the significance these words contained. It was not until afterwards that I remembered the fact that, as we approached the palace, I had looked up at Nikola's window and had seen no sign of him there. As I had not rung the bell, but had been admitted by the old man-servant, how could he have become aware of my presence? But, as I say, I thought of all that afterwards. For the moment the only desire I had was to inform Nikola of my errand.

Upon my entering the room I found Nikola standing before a table on which were glasses, test-tubes, and various chemical paraphernalia. He was engaged in pouring some dark-coloured liquid into a graduating glass, and when he spoke it was without looking round at me.
