"Stephen Harris"s book is the most formidable and scholarly account yet written about British intelligence operations in the Crimean War. The basic conception is original and interesting; the issues are real and clearly conceived; the sources used unrivalled in extent; and the entire treatment rests on an exceptional combination of perspicacity and sensitivity, both of thought about, and feeling for, intelligence operations."
Soldiers of the Queen, Vol. 98 (Sept. 1999)
