The inspiration here arose out of the fact that I was on a cruise like the one described in the story. Some of the events even happened but, I hasten to say, there were no scientific secrets on board as far as I know and no mystery.
One last word. Based on past experience, I am going to get a lot of letters asking me if I intend to write more Black Widowers stories. Let me answer that with a firm and definite: Yes. That, perhaps, will abort the letters.
As a matter of fact, I have at the moment of this writing, completed and sold six more Black Widowers, five to Ellery Queen's Mystery Magazine and one to The Magazine of Fantasy and Science Fiction. You see, then, that it is quite possible that eventually you will be asked to read something entitled More Tales of The Black Widowers.
I hope so, because its' fun writing these stories-and thank you all for reading them.
