I actually met Sue Grafton back in '94, yes, had to say that.
As for the series. I read A-D years ago, borrowed from a friend, then picked up a 'letter' here and there over the years. (This was long before I joined Goodreads.) Just recently I inherited books G-Y, minus 'Q', (which I need to pick up), from a relative who passed away. But yep, these are good reads.
Kinsey Millhone is a great character, tough and gritty, not your 'feminine' kind of woman - I mean does she even own a dress? Maybe one. But she does like men, and this book, 'G is for Gumshoe' shows that in a big way. I won't even go to a scene which really stunned, astonished and totally distracted me. Yep, it's there.
As to the story - or stories - there are two here, overlaid or intersecting plots. First off, Kinsey, native Californian and private investigator, is asked to find a client's elderly mother, last seen out in Arizona living in an area known as the 'Slabs.' (The Slabs could be its own story, IMO.) At the same time Kinsey is watching out for a hired killer - or killers - who are after her for events which occurred earlier. She's hired a bodyguard, and he's great. (He also needs his own book or series.) So, dodging a hitman and looking for a possibly confused little old lady - or is it dementia? - takes Kinsey on a trip to Arizona and back. As for the hitman, he's a real psycho who drags around his little boy wherever he goes. (And that's certainly a different twist, isn't it?)
It's intense. More thriller in places than good old 'standard' mystery and a thoroughly enjoyable read. Kinsey is intense, yet likeable, the kind of person you'd wish were your second best friend. She's funny and shrewd, but knows her weaknesses as well as her strengths. I intend to continue on with Letter H, get the missing Q, and either buy or borrow A-F. That'll keep me busy for a while.
Four stars.
