Mystery fans are mourning Mary Higgins Clark, the “Queen of Suspense” who died last Friday at the age of 92.

Clark, known for novels like Where Are the Children? and Kiss the Girls and Make Them Cry, was one of the genre’s most popular authors, with more than 100 million copies of her books in print in America.

At the Los Angeles Times, author and mystery literature expert Sarah Weinman writes that Clark’s books “embodied the spirit of a tabloid-adoring aunt ready to whisper to you about extraordinary danger just lurking around the corner, waiting to find you.

“One of Clark’s gifts was her unerring generosity towards writers, in her own family and well outside of it,” Weinman writes. “[The] need to write, combined with an unerring, and superbly honed, instinct for what people needed to read, made Clark a grand success for more than four decades.”

On Twitter, author Laura Lippman writes, “Mary Higgins Clark was a trailblazer, so many of us owe our careers to her. My favorite memory is of her at Malice Domestic, dressed exquisitely, stamping her well-shod foot in mock exasperation: ‘You girls now have so much fun.’”

Writer Harlan Coben tweeted, “Heartbroken. A generous mentor, hero, colleague, and friend. She taught me so much. I’ll always be grateful.”

And Christopher Rice writes, “Mary Higgins Clark was a class act. I’ll always treasure the publishing advice she gave me. Ride out the rough patches and don’t get greedy. My heart goes out to her lovely family.”
