The aim of the second edition of Serial Crime is to provide a theoretical and practical overview of criminal profiling and serial crime from a critical point of view. This edition will include revised and expanded chapters from the first edition, as well as a number of new chapters covering concepts not seen elsewhere in any of the literature on the subject matter. This includes a chapter detailing a study on metacognition in criminal profiling, research on the investigative relevance of criminal profiling, and a chapter on behavioral consistency and the homology assumption. These additions will help fill the gaps missing from the previous edition.
