"Certainly not. He was quite an outsider," answered Houston brusquely.
"In that case you are welcome to my conclusions. All the things you have mentioned point to one explanation. This house is haunted by the ghost of Mr. Van Nuysen, and he was a leper."
Houston stood up and stared at his companion.
"What a horrible notion! I must say I fail to see how you have arrived at such a conclusion."
"Take the chain of evidence in rather different order," said Low. "Why should a man tap with a stick?"
"Generally because he's blind."
"In cases of blindness, one stick is used for guidance. Here we have two for support."
"A man who has lost the use of his feet."
"Exactly; a man who has from some cause partially lost the use of his feet."
"But the bladder and the lion-like face?" went on Houston.
"The bladder, or what seemed to us to resemble a bladder, was one of his feet, contorted by the disease and probably swathed in linen, which foot he dragged rather than used; consequently, in passing through a door, for example, he would in the habit of drawing it in after him. Now, as regards the single footmark we saw. In one form of leprosy, the smaller bones of the extremities frequently fall away. The pad-like impression was, as I believe, the mark of the other foot—a toeless foot which he used, because in a more advanced stage of the disease the maimed hand or foot heals and becomes callous."
"Go on," said Houston; "it sounds as if it might be true. And the lion-like face I can account for myself. I have been in China, and have seen it before in lepers."
"Mr. Van Nuysen had been in Trinidad for many years, as we know, and while there he probably contracted the disease."
"I suppose so. After his return," added Houston, "he shut himself up almost entirely, and gave out that he was a martyr to rheumatic gout, this awful thing being the true explanation."
"It also accounts for Mrs. Van Nuysen's determination not to return to her husband."
Houston appeared much disturbed.
"We can't drop it here, Low," he said, in a constrained voice. "There is a good deal more to be cleared up yet. Can you tell me more?"
"From this point I find myself on less certain ground," replied Low unwillingly. "I merely offer a suggestion, remember—I don't ask you to accept it. I believe Mrs. Van Nuysen was murdered!"
"What?" exclaimed Houston. "By her husband?"
"Indications tend that way."
"But, my good fellow—-"
"He suffocated her and then made away with himself. It is a pity that his body was not recovered. The condition of the remains would be the only really satisfactory test of my theory. If the skeleton could even now be found, the fact that he was a leper would be finally settled."
There was a prolonged pause until Houston put another question.
"Wait a minute, Low," he said. "Ghosts are admittedly immaterial. In this instance our spook has an extremely palpable body. Surely this is rather unusual? You have made everything else more or less plain. Can you tell me why this dead leper should have tried to murder you and old Filderg? And also how he came to have the actual physical power to do so?"
Low removed his cigarette to look thoughtfully at the end of it. "Now I lapse into the purely theoretical," he answered. "Cases have been known where the assumption of diabolical agency is apparently justifiable."
"Diabolical agency?—I don't follow you."
"I will try to make myself clear, though the subject is still in a stage of vagueness and immaturity. Van Nuysen committed a murder of exceptional atrocity, and afterwards killed himself. Now, bodies of suicides are known to be peculiarly susceptible to spiritual influences, even to the point of arrested corruption. Add to this our knowledge that the highest aim of an evil spirit is to gain possession of a material body. If I carried out my theory to its logical conclusion, I should say that Van Nuysen's body is hidden somewhere on these premises—that this body is intermittently animated by some spirit, which at certain points is forced to re-enact the gruesome tragedy of the Van Nuysens. Should any living person chance to occupy the position of the first victim, so much the worse for him!"
For some minutes Houston made no remark on this singular expression of opinion.
"But have you ever met with anything of the sort before?" he said at last.
"I can recall," replied Flaxman Low thoughtfully, "quite a number of cases which would seem to bear out this hypothesis. Among them a curious problem of haunting exhaustively examined by Busner in the early part of 1888, at which I was myself lucky enough to assist. Indeed, I may add that the affair which I have recently engaged upon in Vienna offers some rather similar features. There, however, we had to stop short of excavation, by which alone any specific results might have been attained."
"Then you are of the opinion," said Houston, "that pulling the house to pieces might cast some further light upon this affair?"
"I cannot see any better course," said Mr. Low.
Then Houston closed the discussion by a very definite declaration.
"This house shall come down!"
So "The Spaniards" was pulled down.
Such is the story of "The Spaniards," Hammersmith, and it has been given the first place in this series because, although it may not be of so strange a nature as some that will follow it, yet it seems to us to embody in a high degree the peculiar methods by which Mr. Flaxman Low is wont to approach these cases.
The work of demolition, begun at the earliest possible moment, did not occupy very long, and during its early stages, under the boarding at an angle of the landing was found a skeleton. Several of the phalanges were missing, and other indications also established beyond a doubt the fact that the remains were the remains of a leper.
The skeleton is now in the museum of one of our city hospitals. It bears a scientific ticket, and is the only evidence extant of the correctness of Mr. Flaxman Low's methods and the possible truth of his extraordinary theories.
