Here we have three books from the Hawthorne & Horowitz mystery series, written by Anthony Horowitz. These are the first three books in the series, and include one trade paperback and two hardcovers: The Word Is Murder (Book 1, trade paperback) The Sentence Is Death (Book 2, hardcover with dust jacket) A Line To Kill (Book 3, Hardcover with dust jacket) All three books are in excellent condition. The spines are tight and square, and there are no rips, creases or markings inside or out. The dust jackets on the two hardcovers have some edge wear.
