Lots of information entertainingly imparted and a great formula for a natural history book: that鈥檚 Dr Tatiana鈥檚 Sex Advice to All Creation (Vintage, 拢7.99). Here an agony aunt solves problems for creatures small and great from the female hyena worried about her clitoris as large as a phallus to the sponge lice anxious about sneaky cross-dressing males.
Spying rivals is a theme running through Olivia Judson鈥檚 book, but it鈥檚 the other kind of spy (human) that features in Thomas Powers鈥檚 brilliant Intelligence Wars (New York Review Books, 拢9.99), which has just been revised and expanded. The essays 鈥淧hantom spies at Los Alamos鈥� and 鈥淎merica鈥檚 new intelligence war鈥� are together worth the price of the book.
