ALLEN K. YOUNG “Reflection on Murder.” Short story. Professor Posenby #2. First published in Ellery Queen’s Mystery Magazine, October 1968. Presumably never reprinted.

   The tenth rule of Ronald Knox’s Ten Commandments of Detective Fiction says that “twin brothers, and doubles generally, must not appear unless we have been duly prepared for them.” This second of several stories Alan K. Young wrote about retired poetry and code expert Professor Ponsby (no first name known) takes this rule head on and makes an excellent story out of it.

   It doesn’t in any way break the rule, since the fact that Tom and Barnaby Varden are twins is stated up front with no denying it. There is also no denying that one of them murdered their uncle, but which one? Almost no one can tell them apart, so eye witnesses to the fact that one was seen leaving the house at the time of murder are of no value.

   What’s more, the other brother was seen at a boxing match the next town over at the time of the murder, gives one of the two an unshakeable alibi. But which one was which?

   Totally sure that no jury would ever convict either one “beyond a shadow of a doubt,” they boastfully send the following poem to the harried police chief, who comes to Ponsby with it. I hope you can read it:

      

   I believe I have read another story with exactly the premise, but without the poem, and yet, if so, I do not remember where I read it or who wrote it. You may be able to figure it out — all the clues are there — but I am chagrined to say I didn’t. This is a puzzle story only, with only a cursory attempt at characterization, but as such it’s exceedingly well done. It’s like admiring a solidly constructed crossword puzzle at the end of the week in the New York Times. I enjoyed it immensely.

   It probably won’t ever happen, but Young wrote enough Ponsby stories to put together a very decent collection. I’d buy it!

NOTE: Alan K. Young’s papers regarding his short story writing are stored at Columbia University. A short desription of the collection says that the author “is a former junior-college English instructor, with a B. A. in English from Harvard and an M. A. in the same subject from the University of California.”
