Alva rushes through the trees in the dead of night with her sniffer wolf, Fen. Being out alone when there's a kidnapper on the loose is reckless, but if she ever wants to be an investigator like her Uncle Magnus, she'll need to be first to the crime scene. But what Alva discovers raises more questions than it answers, drawing her into a dangerous search for truth, and for treasure.

In this book David Wyatt examines the mythology of California as it is reflected in the literature of the region. He argues that in the literature of the West, the energies, which, in other regions, had been concentrated in covenant theology or the rationalisation of Southern history, are displaced into an encounter with landscape. Tracing the early literature of California to Dana, Leonard, and Fremont, Wyatt studies their development of self-consciousness and awareness of the physical beauty in nature. He then examines in separate chapters the writings of Muir, King, and Mary Austin during a time of domestication and exploitation of the land when landscape became, of necessity, an idea or lost ideal. Of twentieth-century writers, the book focuses on Norris, Steinbeck, and Chandler, who seemed to struggle against the land, charting the advance of human hopes against the vast open spaces of the West. Professor Wyatt concludes with the writer's return to landscape as source and end in the poetry of Jeffers and Snyder.

This study, first published in 1994, looks at the cultural legacy of the sixties through ten creative figures who came of age during the Vietnam War. Wyatt argues that it is each artist's 'personal engagement' with his own era that binds together the achievements of storytellers such as filmmaker George Lucas, songwriter Bruce Springsteen, playwright Sam Shepard, journalist Michael Herr, writers Ann Beattie, Alice Walker, Ethan Mordden, Sue Miller, and poets Gregory Orr and Louise Gluck. For some their work is marked by the war and concerned directly with it; in others, Vietnam represents the prevailing counterculture sensibility often associated with the sixties. Out of the experience new voices emerge - from Michael Herr's landmark invention of a new journalistic voice in his Vietnam War reporting to Bruce Springsteen's tapping of the working class decline in postwar America.

Secret Histories claims that the history of the nation is hidden-in plain sight-within the pages of twentieth-century American literature. David Wyatt argues that the nation's fiction and nonfiction expose a "secret history" that cuts beneath the "straight histories" of our official accounts. And it does so by revealing personal stories of love, work, family, war, and interracial romance as they were lived out across the decades of the twentieth century. Wyatt reads authors both familiar and neglected, examining "double consciousness" in the post-Civil War era through works by Charles W. Chesnutt, W. E. B. Du Bois, and Booker T. Washington. He reveals aspects of the Depression in the fiction of F. Scott Fitzgerald, Anzia Yezierska, and John Steinbeck. Period by period, Wyatt's nuanced readings recover the felt sense of life as it was lived, opening surprising dimensions of the critical issues of a given time. The rise of the women's movement, for example, is revivified in new appraisals of works by Eudora Welty, Ann Petry, and Mary McCarthy. Running through the examination of individual works and times is Wyatt's argument about reading itself.Reading is not a passive activity but an empathetic act of cocreation, what Faulkner calls "overpassing to love." Empathetic reading recognizes and relives the emotional, cultural, and political dimensions of an individual and collective past. And discovering a usable American past, as Wyatt shows, enables us to confront the urgencies of our present moment.

Afterlife: The Strange Fate of Literary Remains explores what happens to a body of work left unpublished or unfinished at the time of a writer's death. In nine chapters, David Wyatt tells the story of the "afterlife" of texts by Shakespeare, William Wordsworth, Charles Dickens, Harriet Jacobs, Emily Dickinson, William Faulkner, Sylvia Plath, Ernest Hemingway, and Ralph Ellison—and of the improbable and unpredictable ways in which literature that might never have seen publication managed to end up on the printed page.Posthumously edited texts raise important issues about the meaning and shape of a literary career. How is one to assess the arc of Ellison's achievement when, after his endlessly reworked second novel finally made it into print in 1999, it was then superseded, in 2010, by another version? Meanwhile, the publication of four Hemingway books after the author's death undid any notion that the writer suffered some sort of decline late in life, and the gender-bending experiments in The Garden of Eden cast a revisionary light back on what had become a deeply reductive belief in the Hemingway Code. While judgments about these writings may begin as technical matters, Wyatt shows that they eventually become aesthetic and, finally, ethical considerations. Despite the difficulties involved, such evaluations continue to be made and to produce the editions that teachers and readers are required to choose among.Throughout Afterlife, Wyatt stresses the attentiveness needed in the editing of posthumous texts: being mindful to honor an author's literary remains by providing an answerable reading of them, while also caring enough about the work left behind to take a position on the printed form it might best take or, if such a conclusion feels impossible, to give a responsible account of why it is out of reach.

An accessible introduction to the concept of the auteur (author) in film theory.Robert Kolker and David Wyatt provide readers with a history of auteur theory, from its initial origins in France in the late 1940s as an outgrowth of the cinematic theories of the French film critics and theorists André Bazin and Alexandre Astruc, to the canonizing work of American film critic Andrew Sarris in the 1960s. After a streamlined account of the various postwar renaissances in film - the shock of “Neorealism”, the “New Wave,” and “New American Cinema” - the book features detailed examinations of the work of forty-eight auteurs, including F.W. Murnau, Jean-Luc Godard, Ida Lupino, Alfred Hitchcock, Yasujirō Ozu, Stanley Kubrick, Spike Lee, Pedro Almodóvar, and Jane Campion. In its focus on a limited number of auteurs, this book aims to offer a map of representative figures rather than an exhaustive or comprehensive list, providing an informative entry point to the study of the auteur.Essential reading for any students of film theory and film studies, particularly those taking classes on the auteur.

In Hemingway, Style, and the Art of Emotion, David Wyatt shows that the work of Ernest Hemingway is marked more by vulnerability and deep feeling than by the stoic composure and ironic remove for which it is widely known. This major reassessment of the shape of Hemingway's career recovers the soul of the author's work, revealing him as a multifaceted writer rather than a cold, static icon. Wyatt claims that Hemingway's famous early style does not embrace emotional reticence but works instead to measure the cost of keeping thoughts and feelings under the surface. By the early 1930s Hemingway also turned away from the art of 'the omitted' and began to develop a vision and style more accommodating of the awkwardness and embarrassments of everyday life. Relying on a thorough knowledge of the vast archive Hemingway left behind at his death, this book shows Hemingway as a thoroughly complex and transmutable figure.

The decade of the 1960s has come to occupy a uniquely seductive place in both the popular and the historical imagination. While few might disagree that it was a transformative period, the United States remains divided on the question of whether the changes that occurred were for the better or for the worse. Some see it as a decade when people became more free; others as a time when people became more lost. American Literature in Transition, 1960-1970 provides the latest scholarship on this time of fateful turning as seen through the eyes of writers as various as Toni Morrison, Gary Snyder, Michael Herr, Amiri Baraka, Joan Didion, Louis Chu, John Rechy, and Gwendolyn Brooks. This collection of essays by twenty-five scholars offers analysis and explication of the culture wars surrounding the period, and explores the enduring testimonies left behind by its literature.
