“ ‘For two days after this Brunton was most assiduous in his attention to his duties. I made no allusion to what had passed and waited with some curiosity to see how he would cover his disgrace. On the third morning, however, he did not appear, as was his custom, after breakfast to receive my instructions for the day. As I left the dining-room I happened to meet Rachel Howells, the maid. I have told you that she had only recently recovered from an illness and was looking so wretchedly pale and wan that I remonstrated with her for being at work.

“ ‘ “You should be in bed,” I said. “Come back to your duties when you are stronger.”

“ ‘She looked at me with so strange an expression that I began to suspect that her brain was affected.

“ ‘ “I am strong enough, Mr. Musgrave,” said she.

“ ‘ “We will see what the doctor says,” I answered. “You must stop work now, and when you go downstairs just say that I wish to see Brunton.”

“ ‘ “The butler is gone,” said she.

“ ‘ “Gone! Gone where?”

“ ‘ “He is gone. No one has seen him. He is not in his room. Oh, yes, he is gone, he is gone!” She fell back against the wall with shriek after shriek of laughter, while I, horrified at this sudden hysterical attack, rushed to the bell to summon help. The girl was taken to her room, still screaming and sobbing, while I made inquiries about Brunton. There was no doubt about it that he had disappeared. His bed had not been slept in, he had been seen by no one since he had retired to his room the night before, and yet it was difficult to see how he could have left the house, as both windows and doors were found to be fastened in the morning. His clothes, his watch, and even his money were in his room, but the black suit which he usually wore was missing. His slippers, too, were gone, but his boots were left behind. Where then could butler Brunton have gone in the night, and what could have become of him now?

“ ‘Of course we searched the house from cellar to garret, but there was no trace of him. It is, as I have said, a labyrinth of an old house, especially the original wing, which is now practically uninhabited; but we ransacked every room and cellar without discovering the least sign of the missing man. It was incredible to me that he could have gone away leaving all his property behind him, and yet where could he be? I called in the local police, but without success. Rain had fallen on the night before, and we examined the lawn and the paths all round the house, but in vain. Matters were in this state, when a new development quite drew our attention away from the original mystery.

“ ‘For two days Rachel Howells had been so ill, sometimes delirious, sometimes hysterical, that a nurse had been employed to sit up with her at night. On the third night after Brunton’s disappearance, the nurse, finding her patient sleeping nicely, had dropped into a nap in the armchair, when she woke in the early morning to find the bed empty, the window open, and no signs of the invalid. I was instantly aroused, and, with the two footmen, started off at once in search of the missing girl. It was not difficult to tell the direction which she had taken, for, starting from under her window, we could follow her footmarks easily across the lawn to the edge of the mere, where they vanished close to the gravel path which leads out of the grounds. The lake there is eight feet deep, and you can imagine our feelings when we saw that the trail of the poor demented girl came to an end at the edge of it.
