Jane Jeffry is definitely a cozy sort: her best friend, Shelly, lives next door, and her kids are adolescent but adorable. In this latest adventure, Jane's boyfriend, Mel the detective, is mostly offstage. Shelly and Jane sign up for a gardening class, but their lecturer, a plant researcher, is severely beaten before it begins. The class goes forward anyway, with a supercilious replacement and an assortment of broadly drawn but vivid types: a take-no-prisoners elderly librarian, a martinet whose pant creases match his tortuous garden geometry, a befuddled fellow who can't get over the death of his wife, a conspiracy freak, and so on. When the offensive replacement lecturer is found dead in his own garden, Jane and Shelly find digging up the connections among these folks to be irresistible. Jane is only slightly hampered by a broken foot, and this time she even treats herself to a TV in the bedroom.--Booklist.
