people who read mysteries tend to have favorites. Two of mine are Sue Grafton (the alphabet lady) and Robert Parker. I have recently noticed, however, my increasing irritation with the style of both of these writers and I'm beginning to wonder (meaning, it may be time to read for writing style as well as for content) if other mystery writers do the same things; one, the excessive and annoying use of the personal pronoun--i.e., "I walked to my door, went out, down my front steps, shrugging into my jacket as I went, out to my new car, etc etc" and, at least in Parker's case, there seems to be a dearth of semicolons. Only once in the first fifteen books did I actually find one, and that seemed to be unavoidable, so he used it.
That, and the fact that any time you write a first person mystery there is a necessity for backstory, (or appears to be), partly to explain the references for new references, but it also is a neat way to pad the pages.
Maybe it's unavoidable, I dunno.
