For decades critics have portrayed August Derleth as an intractable, foolish and at times even villainous man, tainting his legacy in the history of the modern weird tale. This book contains new, comprehensive scholarship, and with sharp arguments and solid evidence John D. Haefele dismisses the criticism and demonstrates why it is time to re-establish Derleth's reputation. Ground-zero of the controversy are Derleth's "posthumous collaborations" with H. P. Lovecraft, involving his pastiches and the debate concerning the Cthulhu Mythos vs. the Derleth Mythos. All this, and much more, John D. Haefele looks at and engagingly analyzes. With surprising, yet convincing, results. It is time to set the record straight. This book belongs on the shelf between Carter's A Look Behind the Cthulhu Mythos and Joshi's The Rise and Fall of the Cthulhu Mythos. A must for anyone interested in Lovecraft, Derleth, Arkham House and the history of the modern weird tale. This is a completely revised, trade paperback edition.
