Forensic Science - An Introduction to Scientific Crime Detection, 2nd edn. (Third Indian Reprint)

The second edition of Dr. Walls book presents a comprehensive and up-to-date picture of the ways in which scientific techniques are used in the operations of the law (especially the criminal law), and of the general background to expert scientific evidence. The author, who was for five years Director of the Metropolitan Police Forensic Science Laboratory, has assumed no scientific background on the readers part, and at the same time has explained fully all the modern technical developments in the subject.

The book has been thoroughly overhauled to incorporate the latest techniques, and much has been added to deal with the important, numerous and in some cases unexpected developments in the subject since the first edition was written. The various important new analytical techniques, and their uses, are fully described; the chapter on toxicology has been rewritten; the subject of blood-alcohol analysis has been re-treated in the light of new legislation, and the very important new advances in blood-grouping methods have been described.

The first edition had an enthusiastic reception from reviewers and readers: ``written in clear, readable language, this book fulfils an important purpose in providing a summary of the modern techniques of forensic science for those like the solicitor who, though professionally involved, are not necessarily technically informed as to the details of the procedures available ... For his chapters on road accidents and on alcohol and the driver alone this book should be read by every solicitor in general court practice`` (Journal of the Law Society of Scotland); ``a fascinating account of the problems which face the police and the methods and instruments used in an attempt to solve these problems, illustrated by a series of excellent plates`` (Law Societys Gazette);`` it is precise, lucid and most satisfyingly logical ... This is the best book of its kind since Paul Kirks or Svenssons classics...a fine modern guide to the principles of scientific crime investigation, most strongly recommended`` (Professor Keith Simpson in the Medico-Legal Journal).

Unique in its scope and written with the needs of the non-specialist in mind, Dr. Walls book will appeal to all those concerned with using forensic science in law enforcement, police officers and lawyers, and those who are interested in embarking on a career in forensic science.
