Ellery Queen

Golden age mystery writer, used as both a pen name for two authors and as the eponymous character.

Tropes used by Ellery Queen:

 * Asshole Victim: Particularly in the television adaptation, the victims often were involved in underhanded dealings, had some sinister secret or were revealed to treat others by anything other than the Golden Rule.
 * Autopsy Snack Time: Doc Proutie has been known to do this.
 * The Boxing Episode: "Mind Over Matter" and "A Matter of Seconds".
 * Canon Immigrant: Ellery's secreatary Nikki Porter was originally created for the radio show, but went on to appear in two of the novels and several short stories.
 * Character Name Alias: In The Origin of Evil, there is a character who calls himself Alfred Wallace. Recognising the connotations of the name (Wallace was a naturalist and contemporary of Darwin who independently proposed a theory of natural selection) is what starts Ellery down the path to the solution of the mystery.
 * Cigar Chomper: Sgt. Veelie
 * Connect the Deaths: Averted in Cat of Many Tails; while the deaths are plotted on the map, the pattern is irrelevant.
 * Corruption of a Minor: The Tragedy of Y
 * Couldn't Find a Pen: In The Scarlet Letters, a dying man uses his own blood to write XY on a wall in an extremely cryptic Dying Clue.
 * Dead Man's Chest: What appears to have happened to the victim in "The Three Rs" in Calendar of Crime.
 * Direct Line to the Author
 * The Disease That Shall Not Be Named: At one point in The Tragedy of Y, the York family doctor lets amateur detective Drury Lane read the family medical history, specifically all the parts that talk about the positive Wasserman tests. The book never uses the word "syphilis". Not even when Lane gets access to those medical files by proving to the doctor that he already knew the York children had been born with the disease.
 * Distaff Counterpart: Murder, She Wrote
 * Driven to Suicide: in Ten Days' Wonder.
 * Dying Message: Many, many variations.
 * Faked Kidnapping
 * Finger-Licking Poison: The Three Widows had a victim being slowly poisoned even though everything she ate and drank was carefully screened beforehand. It turned out the would-be killer was and the poison was
 * Friend on the Force: Ellery's father, Inspector Richard Queen.
 * Horrible Hollywood: The 70s TV episode "The Adventure of the Sinister Scenario" had the Queens, father and son, witness this for themselves when they go on the set of an adaptation of one of Ellery's books. This being an Ellery Queen mystery, this trope's horrible aspects culminate in murder.

 * Informed Flaw: Drury Lane's deafness.
 * Inspector Lestrade: Simon Brimmer in the TV series.
