s the door was closed, however, the mask fell from her
face, and she sank down into a chair with a great sigh, and hid her
eyes with her hand. When I saw that her high spirits had failed, I
at once took advantage of her reaction to make a diagnosis.

"She said to me very sweetly, 'I cannot tell you how I loathe
talking about myself.' I reminded her that a doctor's confidence
was sacred, but that you were grievously anxious about her. She
caught on to my meaning at once, and settled that matter in a word.
'Tell Arthur everything you choose. I do not care for myself, but
for him!' So I am quite free.

"I could easily see that she was somewhat bloodless, but I could not
see the usual anemic signs, and by the chance, I was able to test
the actual quality of her blood, for in opening a window which was
stiff a cord gave way, and she cut her hand slightly with broken
glass. It was a slight matter in itself, but it gave me an evident
chance, and I secured a few drops of the blood and have analysed
them.

"The qualitative analysis give a quite normal condition, and shows,
I should infer, in itself a vigorous state of health. In other
physical matters I was quite satisfied that there is no need for

"I am in doubt, and so have done the best thing I know of. I have
written to my old friend and master, Professor Van Helsing, of
Amsterdam, who knows as much about obscure diseases as any one in
the world. I have asked him to come over, and as you told me that
all things were to be at your charge, I have mentioned to him who
you are and your relations to Miss Westenra. This, my dear fellow,
is in obedience to your wishes, for I am only too proud and happy to
do anything I can for her.

"Van Helsing would, I know, do anything for me for a personal
