This new text by Daniel Mears and Joshua Cochran makes an engaging and important contribution to an increasingly crowded field in criminological and criminal justice (CCJ) research. It is split into four parts: an introduction to CCJ research; essential research ingredients; types of CCJ research; and the charmingly titled ‘Chefs in the Kitchen’. Part I (Chapters 1–3) covers the introduction; science and CCJ research; and initial observations on the science and art of conducting, evaluating and using research. Part II (Chapters 4–6) delves into the respective roles of theory, data and analysis in research; while Part III (Chapters 7–9) considers basic versus applied research, identifying causal effect, and CCJ research areas and topics. Finally, Part IV (Chapters 10 and 11) sets out the criteria for conducting, evaluating, and using research and practical steps in the science and art of doing so.
