The Shape Shifter by Tony Hillerman

For your light reading pleasure let me recommend THE SHAPE SHIFTER by Tony Hillerman.

Legendary Lieutenant Joe Leaphorn is now retired from the Navaho Tribal Police, but is clearly itching to continue working. A long cold case, the possible reappearance of an ancient hand woven rug, and the disappearance of an old acquaintance set Leaphorn on the prowl once again through the backroads of the Four Corners. He is on the trail of a heartless master criminal who seems to take on and then lose identities as rapidly as the Shape Shifters in old Navaho lore. There is ample local color, plenty of Navaho philosophy, a suspenseful conclusion, and a graceful exit that promises more adventures to come from Mr. Hillerman and his resourceful detective. A pleasant and informative read for anyone, but especially pleasing for lovers of the Southwest.
