Title: An excellent and informative insight into surveillance
Review: A very informative book suitable for both people interested in how others can and have been 'spied' upon, and for the technical who want to see how the devices work and even make them.It includes a quantity of circuit diagrams including parts lists for many listening devices, receiving devices and counter surveillance equipment. Although for legal reasons I cannot say whether or not I have tried out the 'bugs', they DO work !
