Historically written book of Canters own experiences of real life criminal behaviour. Canters involvement in criminal pschological profiling describes a science involving, intuition supported by empirical evidence. His interesting and easy writting style allows absorbtion and understanding of the information supplied by avoiding the speciallist statistics and phrases applied in psychology. Canter compairs the British approach to the FBI's profiling, clarifying the differences between them and the reasoning behind these differences. Furthermore, Canter enjoys a relationship with many British Constabularies, something which is rare yet valuable to forensic psychology. Subsequently all of his data is collected from British offenders, to the extent that some discussed cases may be recognised. In summary, pscyhologists are often described as academics in common sense however Canter shows where common sense falls down and less obvious factors predict behaviour, establishing a future for the interpretation of criminal shadows.
