Ruddy Fly, Berners

Midge Flies
Mickey Finn  English  fly
  Canadian streamer. In reference to the origin of this fly pattern, it was mentioned in a letter written by John Alden Knight (Streamers & Bucktails, 1950) and addressed to Joseph (Joe) Bates:
  In 1932, I (John Alden Knight) was invited and went to Greenwich, Connecticut on a fishing trip. Mr. Vanderhoff, the host, handed me a small bucktail streamer, and told me that it was the most effective fly for brook trout. Red and Yellow Bucktail was the name of the fly, and it was an obscure fly that was generally unknown.
  Later, when I went to Toronto in 1936, I fished with Gregory Clark of the Toronto Star newspaper company, and I caught 75 brook trout using only that particular fly in the afternoon. Returning in the car, Clark and I gave this fly the name "Assassin". Clark told me later that he had changed the name of the fly after having read a special report that appeared in Esquire magazine. The report stated that waiters in New York city were jealous of Rudolf Valentino who was a charismatic handsome actor, and they gave Valentino a spiked drink called Mickey Finn. Valentino got sick and died after drinking it. It was contended that Mickey Finn drove Valentino to his death.
  It is surely an attractive naming of the fly, meaning if this fly is swallowed, it works like a deadly loaded drink. When Clark wrote about these circumstances to Hunting and Fishing Magazine in 1937, the fly's reputation instantly exploded into fame. All the Mickey Finns in New York city were sold out, and the Weber Company received orders of 1 million Mickey Finns from all over the United States.
  Incidentally, the result of a brief investigation about the origin of the word Mickey Finn revealed that apparently it was the name of an Irish man, and also the name of a bar in New York or in Chicago. It was said that the man was disliked by people, and that they gave him alcohol containing a purgative (croton oil) to knock him out. This story circulated quickly and widely, and finally loaded alcohol has come to be called Mickey Finn.
