Small-time stoolie, Jake " The Spinner" Jablon, made a lot of new enemies when he switched careers, from informer to blackmailer. And the more "clients", he figured, the more money -- and more people eager to see him dead. So no one is surprised when the pigeon is found floating in the East River with his skull bashed in.And what's worse, no one cares -- except Matthew Scudder. The ex-cop-turned-private-eye is no conscientious avenging angel. But he's willing to risk his own life and limb to confront Spinner's most murderously aggressive marks. A job's a job after all -- and Scudder's been paid to find a killer -- by the victim...in advance.

The Professor and the Madman , masterfully researched and eloquently written, is an extraordinary tale of madness, genius, and the incredible obsessions of two remarkable men that led to the making of the Oxford English Dictionary -- and literary history. The compilation of the OED , begun in 1857, was one of the most ambitious projects ever undertaken. As definitions were collected, the overseeing committee, led by Professor James Murray, discovered that one man, Dr. W. C. Minor, had submitted more than ten thousand. When the committee insisted on honoring him, a shocking truth came to light: Dr. Minor, an American Civil War veteran, was also an inmate at an asylum for the criminally insane.

Bernie Rhodenbarr is a personable chap, a good neighbor, a passable poker player. His chosen profession, however, might not sit well with some. Bernie is a burglar, a good one, effortlessly lifting valuables from the not-so-well-protected abodes of well-to-do New Yorkers like a modern-day Robin Hood. (The poor, as Bernie would be the first to tell you, alas, have nothing worth stealing.) He's not perfect, however; he occasionally makes mistakes. Like accepting a paid assignment from a total stranger to retrieve a particular item from a rich man's apartment. Like still being there when the cops arrive. Like having a freshly slain corpse lying in the next room, and no proof that Bernie isn't the killer. Now he's really got his hands full, having to locate the true perpetrator while somehow eluding the police -- a dirty job indeed, but if Bernie doesn't do it, who will?

Wives & Lovers is a collection of three short novels from the author whom the Boston Globe calls "one of the most expert and substantial of our writers."Requisite Kindness -- published here for the first time -- tells the story of a man who must come to terms with a life of treating women badly when he goes to live with his sister and dying mother. Rare & Endangered Species demonstrates how a wife and mother's suicide reverberates in the small community where she lived, and affects the lives of people who don't even know her. Finally, Spirits is about the pain that men and women can -- and do -- inflict upon each other. These three very different works illuminate the unadorned core of love -- not the showy, more celebrated sort but what remains when lust, jealousy, and passion have been stripped away.

Ya-Yas in Bloom reveals the roots of the Ya-Yas' friendship in the 1930s, following Vivi, Teensy, Caro and Necie through sixty years of marriage, child-raising, and hair-raising family secrets. When four-year-old Teensy Whitman prisses one time too many and stuffs a big old pecan up her nose, she sets off the chain of events that lead Vivi, Teensy, Caro, and Necie to become true sister-friends. Using as narration the alternating voices of Vivi and the Petite Ya-Yas, Siddalee and Baylor Walker, as well as other denizens of Thornton, Louisiana, Wells show us the Ya-Yas in love and at war with convention. Through crises of faith and hilarious lapses of parenting skills, brushes with alcoholism and glimpses of the dark reality of racial bigotry, the Ya-Ya values of unconditional loyalty, high style, and Louisiana sass shine through. But in the Ya-Yas' inimitable way, these four remarkable women also teach their children about the Mysteries: the wonder of snow in the deep South, the possibility that humans are made of stars, and the belief that miracles do happen. And they need a miracle when old grudges and wounded psyches lead to a heartbreaking crime...and the dynamic web of sisterhood is the only safety net strong enough to hold families together and endure. After two bestsellers and a blockbuster movie, the Ya-Yas have become part of American culture -- icons for the power of women's friendship. Ya-Yas in Bloom continues the saga, giving us more Ya-Ya lore, spun out in the rich patois of the Louisiana bayou country and brim full of the Ya-Ya message to embrace life and each other with joy.
