"Speak a little more explicitly," he said.

The doctor removed his pince-nez and looked at him with his eyes half-closed, as is the way of people afflicted with short sight.

"Any further explanation between us would be superfluous. I have ascertained that Elaine Robertson is here. I am her guardian, appointed as such by reason of her father's dementia. As such I tender you my thanks for the shelter you have given her and I intend to take her away immediately; my motor is waiting."

Wallion reflected for a while. He gave Tom a meaning look, for here undoubtedly was a step towards the solution of the problem. In any case the girl must go, for this aggressive and amazing doctor was certainly in the right.

"So you affirm that her father is out of his mind?" he asked; "will you not give us a little more information?"

"Do you know what 'Phantom-Mania' is?" answered the doctor. "Delusions about mysteries which are non-existent ... a fear of pursuers who are not there ... a love for sending messages and gifts which mean nothing. Only the overwrought brain of a neurotic girl can give credence to these. The actions of a weak-minded man or the whims and fancies of a nervous young woman ... both have a fictitious value."

"The death of Victor Dreyel, the stab in the girl's arm, the attack in Captain Street and the theft of the wooden dolls were not delusions."

"I am not concerned with what has occurred here. Elaine accidentally crossed the path of an unknown robber ... it is always the unexpected which happens and such contingencies are from the devil."

"Is that all you have to say about it?"

"Yes, I know what I am talking about, Mr. Wallion, and I don't allow myself to be caught unawares. I am here in the capacity of William Robertson's medical adviser and Elaine's guardian, and I desire to see her at once." His tone had a touch of increased sharpness in it.
