This most usually consists of presenting to the reader ‘a clinical case’ and then setting questions about it, as if in real clinical practice – thereby effectively simulating ‘on paper’ clinical investigation and decision-making. Usually, this is pursued by first describing a clinical presentation – perhaps with the results of some investigations already gained being given – and then inviting the reader to decide how they would, in real practice, proceed. The reader is then invited to ‘turn the page’ in order to read a suggested approach, or more than one approach, to addressing the case. Hence, whereas a textbook offers information, a ‘casebook’ teaches about the use of information. We have adopted this method in the Casebook you are about to use. And in doing so, we have directly linked the book with the second edition of the Handbook of Forensic Psychiatric Practice in Capital Cases,2 so that the two volumes are ‘companion books’, and should be read in conjunction with each other. The Casebook is concerned with both clinical assessment and preparing and presenting expert evidence directed at one or more legal questions, so that the ‘case set’ usually addresses several inter-linking issues.
