have a dagger ready in his
hand? A dagger, or even a sharp knife, seemed out of keeping with the age
in which we lived; and a gentleman landing from his yacht on the shore of
his own estate, even although it was at night and with some mysterious
circumstances, does not usually, as a matter of fact, walk thus prepared
for deadly onslaught. The more I reflected, the further I felt at sea. I
recapitulated the elements of mystery, counting them on my fingers: the
pavilion secretly prepared for guests; the guests landed at the risk of
their lives and to the imminent peril of the yacht; the guests, or at
least one of them, in undisguised and seemingly causeless terror;
Northmour with a naked weapon; Northmour stabbing his most intimate
acquaintance at a word; last, and not least strange, Northmour fleeing
from the man whom he had sought to murder, and barricading himself, like a
hunted creature, behind the door of the pavilion. Here were at least six
separate causes for extreme surprise; each part and parcel with the
others, and forming all together one consistent story. I felt almost
ashamed to believe my own senses.

As I thus stood, transfixed with wonder, I began to grow painfully
conscious of the injuries I had received in the scuffle; skulked round
among the sand hills; and, by a devious path, regained the shelter of the
wood. On the way, the old nurse passed again within several yards of me,
still carrying her lantern, on the return journey to the mansion house of
Graden. This made a seventh suspicious feature in the case. Northmour and
his guests, it appeared, were to cook and do the cleaning for themselves,
while the old woman continued to inhabit the big empty barrack among the
policies. There must surely be great cause for secrecy, when so many
inconveniences were confronted to preserve it.

So thinking, I made my way to the den. For greater security, I trod out
the embers of the fire, and lighted my lantern to examine the wound upon
my shoulder. It was a trifling hurt, although it bled somewhat freely, and
I dressed it as well as I could (for its position made it difficult to
reach) with some rag and cold water from the spring. While I was thus
busied, I mentally declared war against Northmour and his mystery. I am
not an angry man by nature, and I believe there was more curiosity than
resentment in my heart. But war I certainly declared; and, by way of
preparation, I got out my revolver, and, having drawn the cha
