Have Dean Koontz and Bernhard Schlink both written at least one novel?
Dean Koontz Dean Ray Koontz (born July 9, 1945) is an American author. His novels are broadly described as suspense thrillers, but also frequently incorporate elements of horror, fantasy, science fiction, mystery, and satire. Many of his books have appeared on "The New York Times" Bestseller List, with 14 hardcovers and 14 paperbacks reaching the number-one position. Koontz wrote under a number of pen names earlier in his career, including "David Axton", "Leigh Nichols", and "Brian Coffey".
Any God Will Do Any God Will Do, first published by Random House in 1966, is the sixth book by the American satirist and political novelist Richard Condon. After the almost unmitigated grimness of his previous book, "An Infinity of Mirrors", it was a return to his more usual light-heartedness as displayed in works such "A Talent for Loving". Although its theme is madness, unusually for Condon it has little of the almost gratuitous scenes of violence and sudden deaths that punctuate most of his books—the only notable instance being that of a haughty French "sommelier" who shoots himself at an aristocratic dinner party when he discovers that an American guest is indeed correct in asserting that a great white Burgundy can accompany young spring lamb.
