本文以明代公案小說集為範疇，聚焦於惡僧故事的題材承衍與改寫，如何反映公案的明僧故事時代性。從公案小說集的故事分布與案件類型的側重，注意到了題材來源選擇特別著重於法家書與筆記小說，又為後來豔情小說與其他通俗小說所援引。從內容改寫發現，不論源於法家書類型或其他類型小說者，皆在形式增入三詞（告詞、訴詞、判詞），內容增衍判案的內容，說明公案小說在惡僧故事傳播的關鍵位置，亦更加說明公案惡僧題材在擇選與改寫是成功的。明代惡僧公案的時代性體現於當代時聞抄撮、明代故事數量、案件反映內容三方面。公案小說的惡僧題材演繹的歷時性演變，具有文學發展的意義外，明代公案集著重於人命類、姦情類與威逼類案件，反映社會的強烈批判面向。
