Malvika Singh&rsquos perpetual city, a potted history of Delhi in bijou packaging, is the latest in Aleph Book Company&rsquos &lsquoshort biography&rsquo series. The commissioning editor has made some canny choices &mdash Amitava Kumar on Patna Naresh Fernandes on Bombay Indrajit Hazra on Calcutta Mushirul Hasan on Lucknow forthcoming &mdash and Singh, &lsquoMala&rsquo to her friends, is another clever choice the consummate insider writing about the most insidery of cities, a city that prizes connections and who you know. And Singh, publisher of the thoughtful, quasi-academic monthly magazine Seminar, knows everyone.
