Margaret Ellis Millar (née Sturm) was an American-Canadian mystery and suspense writer. Born in Kitchener, Ontario, she was educated there and in Toronto. She moved to the United States after marrying Kenneth Millar (better known under the pen name Ross Macdonald). They resided for decades in the city of Santa Barbara, which was often utilized as a locale in her later novels under the pseudonyms of San Felice or Santa Felicia. Millar's books are distinguished by sophistication of characterization. Often we are shown the rather complex interior lives of the people in her books, with issues of class, insecurity, failed ambitions, loneliness or existential isolation or paranoia often being explored with an almost literary quality that transcends the mystery genre. Unusual people, mild societal misfits or people who don't quite fit into their surroundings are given much interior detail. In some of the books we are given chilling and fascinating insight into what it feels like to be losing touch with reality and evolving into madness. In general, she is a writer of both expressive description and yet admirable economy, often ambitious in the sociological underpinnings of the stories and the quality of the writing. Millar often delivers effective and ingenious "surprise endings," but the details that would allow the solution of the surprise have usually been subtly included, in the best genre tradition. One of the distinctions of her books, however, is that they would be interesting, even if you knew how they were going to end, because they are every bit as much about subtleties of human interaction and rich psychological detail of individual characters as they are about the plot. Millar was a pioneer in writing intelligently about the psychology of women. Even as early as the '40s and '50s, her books have a very mature and matter-of-fact view of class distinctions, sexual freedom and frustration, and the ambivalence of moral codes depending on a character's economic circumstances. Her earliest novels seem unusually frank. Read against the backdrop of Production Code-era movies of the time, they remind us that life as lived in the '40s and '50s was not as black-and-white morally as Hollywood would have us believe. While she was not known for any one recurring detective (unlike her husband, whose constant gumshoe was Lew Archer), she occasionally used a detective character for more than one novel. Among her occasional ongoing sleuths were Canadians Dr. Paul Prye (her first invention, in the earliest books) and Inspector Sands (a quiet, unassuming Canadian police inspector who might be the most endearing of her recurring inventions). In the California years, a few books featured either Joe Quinn, a rather down-on-his-luck private eye, or Tom Aragorn, a young, Hispanic lawyer. Sadly, most of Millar's books are out of print in America, with the exception of the short story collection The Couple Next Door and two novels, An Air That Kills and Do Evil In Return, that have been re-issued as classics by Stark House Press in California. In 1956 Millar won the Edgar Allan Poe Awards, Best Novel award for Beast in View. In 1965 she was awarded the Woman of the Year Award by the Los Angeles Times. In 1983 she was awarded the Grand Master Award by the Mystery Writers of America in recognition of her lifetime achievements.

Julia Clara Catharine Dolores Birk Olsen Hitchens, better known as Dolores Hitchens, was an American mystery novelist who wrote prolifically from 1938 until her death. She also wrote under the pseudonyms D.B. Olsen, Dolan Birkley and Noel Burke. Hitchens collaborated on five railroad mysteries with her second husband, Bert Hitchens, a railroad detective, and also branched out into other genres in her writing, including Western stories. Many of her mystery novels centered around a spinster character named Rachel Murdock. Hitchens wrote Fool's Gold, the 1958 novel adapted by Jean-Luc Godard for his film Bande à part (Band of Outsiders, 1964).

Patricia Highsmith was an American novelist who is known mainly for her psychological crime thrillers which have led to more than two dozen film adaptations over the years. She lived with her grandmother, mother and later step-father (her mother divorced her natural father six months before 'Patsy' was born and married Stanley Highsmith) in Fort Worth before moving with her parents to New York in 1927 but returned to live with her grandmother for a year in 1933. Returning to her parents in New York, she attended public schools in New York City and later graduated from Barnard College in 1942. Shortly after graduation her short story 'The Heroine' was published in the Harper's Bazaar magazine and it was selected as one of the 22 best stories that appeared in American magazines in 1945 and it won the O Henry award for short stories in 1946. She continued to write short stories, many of them comic book stories, and regularly earned herself a weekly $55 pay-check. During this period of her life she lived variously in New York and Mexico. Her first suspense novel 'Strangers on a Train' published in 1950 was an immediate success with public and critics alike. The novel has been adapted for the screen three times, most notably by Alfred Hitchcock in 1951. In 1955 her anti-hero Tom Ripley appeared in the splendid 'The Talented Mr Ripley', a book that was awarded the Grand Prix de Litterature Policiere as the best foreign mystery novel translated into French in 1957. This book, too, has been the subject of a number of film versions. Ripley appeared again in 'Ripley Under Ground' in 1970, in 'Ripley's Game' in 1974, 'The boy who Followed Ripley' in 1980 and in 'Ripley Under Water' in 1991. Along with her acclaimed series about Ripley, she wrote 22 novels and eight short story collections plus many other short stories, often macabre, satirical or tinged with black humour. She also wrote one novel, non-mystery, under the name Claire Morgan , plus a work of non-fiction 'Plotting and Writing Suspense Fiction' and a co-written book of children's verse, 'Miranda the Panda Is on the Veranda'. She latterly lived in England and France and was more popular in England than in her native United States. Her novel 'Deep Water', 1957, was called by the Sunday Times one of the "most brilliant analyses of psychosis in America" and Julian Symons once wrote of her "Miss Highsmith is the writer who fuses character and plot most successfully ... the most important crime novelist at present in practice." In addition, Michael Dirda observed "Europeans honoured her as a psychological novelist, part of an existentialist tradition represented by her own favorite writers, in particular Dostoevsky, Conrad, Kafka, Gide, and Camus." She died of leukemia in Locarno, Switzerland on 4 February 1995 and her last novel, 'Small g: a Summer Idyll', was published posthumously a month later. Gerry Wolstenholme July 2010

Dorothy B. Hughes (1904–1993) was a mystery author and literary critic. Born in Kansas City, she studied at Columbia University, and won an award from the Yale Series of Younger Poets for her first book, the poetry collection Dark Certainty (1931). After writing several unsuccessful manuscripts, she published The So Blue Marble in 1940. A New York–based mystery, it won praise for its hardboiled prose, which was due, in part, to Hughes’s editor, who demanded she cut 25,000 words from the book. Hughes published thirteen more novels, the best known of which are In a Lonely Place (1947) and Ride the Pink Horse (1946). Both were made into successful films. In the early fifties, Hughes largely stopped writing fiction, preferring to focus on criticism, for which she would go on to win an Edgar Award. In 1978, the Mystery Writers of America presented Hughes with the Grand Master Award for literary achievement.
