There are personal files dealing with about 120 double-cross agents in M.I.5 records. Many of the cases never developed, others were of no great importance, and some, such as COBWEB and BEETLE in Iceland and MOONBEAM in Canada, did not operate from the U.K. It would therefore serve no useful purpose to make mention of all the cases. The list which follows gives brief details of some of the more interesting of these cases which were operated from this country. In this list w/t stands for wireless telegraphy; s/w for communication in secret ink or by microphotography; p/c for personal contact in neutral or enemy countries.
