(4) 4-6 Velocity: Classified series. After briefly setting the historical context, this book features eight profiles of nine spies operating on both sides, including six women. Archival photos and reproductions (mostly black-and-white) accompany the readable chapters, which sometimes end abruptly. The pages are busy with images, text boxes, keyword definitions, and unnecessary graphics, but this is an accessible glimpse at a high-interest topic. Reading list. Glos., ind.
