How to drive your teacher wild...
... use Terry Pratchett's 'Guards!' series as an example of Police Procedure and Hardboiled detective genres.
The following books (in order of first to latest) comprise Terry Pratchett's (Discworld) 'Guards!' series:
Guards! Guards! - About a cult who seek to over throw the Patrician by summoning a Dragon and then 'slaying' it, as such re-instating Ankh-Morpork's monarchy with the person who 'slew' the dragon as king.
Contains: Conspiracies to over throw the government, treason, numerous 'dragon-related' murders, and a few accidental deaths.
Men At Arms - About a series of murders committed by a madman who has stolen Discworld's first fire-arm. Rather interesting word of wisdom towards the end about murder.
Contains: Numerous assassinations, theft, murders (including the death of a Watchman and a murder committed by the Watch), attempted murders, and plot to overthrow the government.
Feet of Clay - About freedom and murder of unliving objects. The first murder is particually interesting (and will grab the eye of an english teacher when you mention it) and accidental attempted murder/assassination of the Patrician.
Contains: Attempted assassination, theft, attempted murder, numerous actual murders and a conspiracy (anyone noticing a pattern here?).
Jingo - Not so much crime fiction really apart from the death of a Prince and then the war between Ankh Morpork and Klatch. Vimes (head of the watch) is sacked from the Watch, the Patrician creates his own conspiracy and the ending is quite amusing.
Contains: An assassination and a conspiracy.
The Fifth Elephant - About a plot involving the dwarves of Uberwald created by the werewolf rulers.
Contains: Murder (the final murder is particually good and is committed by a watchman. Pratchett then goes on to actually show that not all hardboiled detectives are so blaize about killing others), attempted murder, theft, the gloomy pants of uncle vanya, the trousers of time and conspiracy to incite war.
If anyone else has read any of those books feel free to comment in more detail on your thoughts as to their use as supplimentary texts for Crime Fiction.
The Maltese Falcon isn't a bad movie, my class watched it just to get a real feel for the noir genre.
