The New York Times bestselling guide to thinking like literature's greatest detective. "Steven Pinker meets Sir Arthur Conan Doyle" (Boston Globe), by the author of The Confidence Game. No fictional character is more renowned for his powers of thought and observation than Sherlock Holmes. But is his extraordinary intellect merely a gift of fiction, or can we learn to cultivate these abilities ourselves, to improve our lives at work and at home? We can, says psychologist and journalist Maria Konnikova, and in Mastermind she shows us how. Beginning with the “brain attic”—Holmes’s metaphor for how we store information and organize knowledge—Konnikova unpacks the mental strategies that lead to clearer thinking and deeper insights. Drawing on twenty-first-century neuroscience and psychology, Mastermind explores Holmes’s unique methods of ever-present mindfulness, astute observation, and logical deduction. In doing so, it shows how each of us, with some self-awareness and a little practice, can employ these same methods to sharpen our perceptions, solve difficult problems, and enhance our creative powers. For Holmes aficionados and casual readers alike, Konnikova reveals how the world’s most keen-eyed detective can serve as an unparalleled guide to upgrading the mind.

Double-cross mazes are even more maddening and mind-bending than the mazes in the author's previous top-selling books, "Maze Mania, Monster Mazes" and "Mastermind Mazes!" In this new type of maze, puzzle-solvers must go "behind-the-scenes" to solve each deluxe, full-color maze. Full-color illustrations.

A colorful square, dissected into four parts, with hinges marked in black. If you leave the blue piece fixed and swing the others around their hinges, a new shape will emerge. Can you guess just by looking what it will be? This is just one of the tricky geometrical gems that will make a puzzler’s mind work overtime. Try drawing a set of variously shaped polygons using only a compass and a ruler (no measuring allowed!), figuring out which of two sculptures is bigger (logic alone won’t give you the answer), and lots more.

"The Maze opens with Corey ... in forced retirement from his last job as a Federal Agent with the Diplomatic Surveillance Group. Corey is restless and looking for action, so when his former lover, Detective Beth Penrose, appears with a job offer, Corey has to once again make some decisions about his career-and about reuniting with Beth Penrose. Inspired by, and based on the actual and still unsolved Gilgo Beach murders, The Maze takes the reader on a dangerous hunt for an apparent serial killer who has murdered nine-and maybe more-prostitutes and hidden their bodies in the thick undergrowth on a lonely stretch of beach. As Corey digs deeper into this case, which has made national news, he comes to suspect that the failure of the local police to solve this sensational case may not be a result of their inexperience and incompetence-it may be something else. Something more sinister." --

Set in Guatemala and based on a true story, “this intriguing literary thriller will appeal to lovers of international crime fiction” (Booklist). Guillermo Rosensweig is a member of the Guatemalan elite, runs a successful law practice, has a wife and kids—and a string of gorgeous lovers. Then one day he crosses paths with Maryam, a Lebanese beauty with whom he falls desperately in love . . . to the point that when he loses her, he sees no other option than to orchestrate his own death. The Mastermind is based on the bizarre real-life story of Rodrigo Rosenberg, a Guatemalan attorney who, in 2009, planned his own assassination after leaving behind a video accusing Guatemalan president Álvaro Colom of his murder. This is a fascinating depiction of modern-day Guatemala and the corrupt, criminal, and threatening reality that permeates its society. “Engaging . . . Raw and unforgettable.” —Publishers Weekly “This is a compelling story that can easily be read in a single sitting. And, as in any good mystery, when things go wrong, the novel becomes that much more interesting. Even for readers with no interest in Guatemala per se, this is one worth reading for the sheer joy of the writing itself.” —Reviewing the Evidence “A riveting account of one man’s high-stakes journey to self-reckoning.” —Cristina García, author of Dreaming in Cuban
