内容简介：
The idea that the extraordinary narrative which has been called the Joyce-Armstrong Fragment is an elaborate practical joke evolved by some unknown person, cursed by a perverted and sinister sense of humour, has now been abandoned by all who have examined the matter. The most macabre and imagi-native of plotters would hesitate before linking his morbid fancies with the unquestioned and tragic facts which reinforce the statement. Though the assertions contained in it are amazing and even monstrous, it is none the less forcing itself upon the general intelligence that they are true, and that we must readjust our ideas to the new situation. This world of ours appears to be separated by a slight and precarious margin of safety from a most singular and unexpected danger. I will endeavour in this narrative, which reproduces the original document in its necessarily somewhat fragmentary form, to lay before the reader the whole of the facts up to date, prefacing my statement by saying that, if there be any who doubt the narrative of Joyce-Armstrong, there can be no question at all as to the facts concerning Lieutenant Myrtle, R. N., and Mr. Hay Connor, who undoubtedly met their end in the manner described.
