The unknown guest

1 My Essay on Death[1] led me to make a conscientious enquiry into the present position of the great mystery, an enquiry which I have endeavoured to render as complete as possible. I had hoped that a single volume would be able to contain the result of these investigations, which, I may say at once, will teach nothing to those who have been over the same ground and which have nothing to recommend them except their sincerity, their impartiality and a certain scrupulous accuracy.
