"I am sure of it," said Cyril.

"Very good. Assuming, therefore, that Lady Wilmersley is sane, we will proceed to draw logical inferences from her actions." Judson paused a moment before continuing: "Now I am convinced that the only connection Prentice had with the affair was to procure some clothes for her mistress, and these had probably been sometime in the latter's possession."

"H'm!" ejaculated Cyril sceptically. "I think it would have been pretty difficult to have concealed anything from that maid of hers."

"Difficult, I grant you, but not impossible, my lord."

"But if Prentice had no knowledge of the tragedy, why did she not return to the castle? What has become of her? Why have the police been unable to find her?"

"I believe that she joined her lover and that they are together on the continent, for in Plumtree I was told that the young man had recently gone to Paris. As I am sure that she knows nothing of any importance, I thought it useless to waste time and money trying to discover their exact locality. That the police have not succeeded in finding her, I ascribe to the fact that they are looking for a young woman who left Newhaven after and not before the murder."

"You think she left before?"

"Yes, and I have two reasons for this supposition. First, I can discover no place where he or she, either separately or together, could have spent the night. Secondly, if they had left Newhaven the following morning or in fact at any time after the murder, they would certainly have been apprehended, as all the boats and trains were most carefully watched."

"But no one knew of her disappearance till twenty-four hours later, and during that interval she could easily have got away unobserved."

"No, my lord, there you are mistaken. From the moment that the police were notified that a crime had been committed, every one, especially every woman, who left Newhaven was most attentively scrutinised."
