a rush of gas from the week-old corpse. We doctors, who have had to study our dangers, have to become accustomed to such things, and I drew back towards the door. But the Professor never stopped for a moment; he sawed down a couple of feet along one side of the lead coffin, and then across, and down the other side. Taking the edge of the loose flange, he bent it back towards the foot of the coffin, and holding up the candle into the aperture, motioned to me to look.

I drew near and looked. The coffin was empty.

It was certainly a surprise to me, and gave me a considerable shock, but Van Helsing was unmoved. He was now more sure than ever of his ground, and so emboldened to proceed in his task. "Are you satisfied now, friend John?" he asked.

I felt all the dogged argumentativeness of my nature awake within me as I answered him:"I am satisfied that Lucy’s body is not in that coffin; but that only proves one thing."

"And what is that, friend John?"

Then he told me to watch at one side of the churchyard whilst he would watch at the other. I took up my place behind a yew-tree, and I saw his dark figure move until the intervening headstones and trees hid it from my sight.

It was a lonely vigil. Just after I had taken my place I heard a
