In the course of this novel a number of well-known persons make their appearance, some of them living, some dead; they appear under their own names, and what is said about them is factually correct.
There are other characters which are fictitious, and in these cases the author has gone out of his way to avoid seeming to point at real persons. He has given them unlikely names, and hopes that no persons bearing such names exist. But it is impossible to make sure; therefore the writer states that, if any such coincidence occurs, it is accidental. This is not the customary "hedge clause" which the author of a roman a clef publishes for legal protection; it means what it says and is intended to be so taken.
Various European concerns engaged in the manufacture of munitions have been named in the story, and what has been said about them is also according to the records. There is one American firm, and that, with all its affairs, is imaginary. The writer has done his best to avoid seeming to indicate any actual American firm or family.
