G is for Gumshoe is the seventh book in Sue Grafton's alphabet mystery series. As always, Grafton's private eye, Kinsey Millhone is hired to take on a seemingly routine investigation, in this case to locate Agnes Grey, her client's elderly mother. As usual, the case is far from straightforward and predictably, Kinsey discovers long buried family secrets. Meanwhile, Kinsey learns that a contract has been taken out on her life by a jailed killer who wants revenge for the role that Kinsey played in his convition. After an initial attempt on her life leaves her badly injured, Kinsey hires Robert Dietz, a professional security expert and body guard to protect her while she continues to work for her own client.
It is amusing to find the fiercely independent Kinsey rely on someone else and chafe under Dietz's take charge attitude, nevertheless they quickly becomes romantically involved. The romantic pairing of a body guard and a fiesty female client is a tired cliché. Is there any chance they won't become involved? The mystery of the missing Agnes Grey, which obviously relies on names associated with the Bronte sisters as clues, is not really that suspenseful. It functions as a reason for Kinsey to publicly continue with her work and therefore, provide the hitman with ample opportunity to strike. Since two stories are not obviously connected, Grafton has the challenge of switching from one mystery to the other. The result is that both mysteries lose some momentum by the novel's conclusion when both plots abruptly converge.
