Upstairs in the pastor’s study, Muller sat in the armchair attentively watching the gyrations of a spinning top. The little toy, started at a certain point, drew a line exactly parallel to the scratch on the floor that had excited his thoughts and absorbed them day and night.
“It was a top--a top” repeated the detective to himself again and again. “I don’t see why I didn’t think of that right away. Why, of course, nothing else could have drawn such a perfect curve around the room, unhindered by the legs of the desk. Only I don’t see how a toy like that could have any connection with this cruel and purposeless murder. Why, only a fool--or a madman--”
Muller sprang up from his chair and again a sharp shrill whistle came from his lips. “A madman!--” he repeated, beating his own forehead. “It could only have been a madman who committed this murder! And the pastor was not the first, there were two other murders here within a comparatively short time. I think I will take advantage of Dr. Orszay’s invitation.”
Half an hour later Muller and the doctor sat together in a summer-house, from the windows of which one could see the park surrounding the asylum to almost its entire extent. The park was arranged with due regard to its purpose. The eye could sweep through it unhindered. There were no bushes except immediately along the high wall. Otherwise there were beautiful lawns, flower beds and groups of fine old trees with tall trunks.
As would be natural in visiting such a place Muller had induced the doctor to talk about his patients. Dr. Orszay was an excellent talker and possessed the power of painting a personality for his listeners. He was pleased and flattered by the evident interest with which the detective listened to his remarks.
“Then your patients are all quite harmless?” asked Muller thoughtfully, when the doctor came to a pause.
“Yes, all quite harmless. Of course, there is the man who strangely enough considers himself the reincarnation of the famous French murderer, the goldsmith Cardillac, who, as you remember, kept all Paris in a fervour of excitement by his crimes during the reign of Louis XIV. But in spite of his weird mania this man is the most good-natured of any. He has been shut up in his room for several days now. He was a mechanician by trade, living in Budapest, and an unsuccessful invention turned his mind.”
