KILLER HEAT. By Linda Fairstein. Doubleday, 2008. 384 pages. $26 hardcover.
Killer Heat, like any good title, is a play on words. It refers to death by New York oven — the baking August temperatures that send the rich to the Hamptons or the Vineyard, and the poor to their fire escapes for a breath of nighttime air. Killer Heat is also a reference to an actual killer or killers and to the heat, slang for law, that hunts ’em down and brings ’em to justice.
