CP/M on an Apple II ?

So I was listenting to a radio play (a police investigation/drama) on the CBC (Canadian Broadcasting Corp.) today in which the plot centred around recovering data (the offshore bank account #, how cliche) from the dead guy's ancient Apple II/e. (The dead guy was apparently like a lot of people on this list: still used an old machine for his main/daily computing ...just so you all know you're actually getting portrayal in the popular arts :/ ) Well, that went by me OK, then they threw in the plot twist: the guy wasn't using the standard OS, he was using an oddball system which was going to make the data recovery more problematic, that system being CP/M. At this point my pedantic-critic bells went off. So somebody either confirm my pedanticism or show me up as the ignorant one: nobody ever bothered to rewrite CP/M (which to my understanding was all targeted to Intel procs) for the Apple II did they? ... maybe the scriptwriting 'computing consultant' figured it would be a good inside joke, ... maybe it's somebody on this list!
