This, the fourth in the enormously pleasurable series starring Botswana's only Lady Detective, finds our hero, Precious Ramotswe, grappling with a dead hoopoe in the garden, a competing Satisfaction Guaranteed Detective Agency and the aspirations of her assistant (to open the aforementioned typing school). She's also moved her business into her fiance's garage. If it weren't for all these complications, she might have already been wed.  (BOT17, $12.95)
