Kristie Macrakis begins by describing how she unearthed a formula for invisible ink in the Stasi archives, which inspired her to pen this history of secret writing, from the simple but ingenious techniques used in ancient Greece and Rome to the newest opportunities for concealment provided by computer files and DNA microdots. In an appendix she offers a selection of recipes for invisible inks derived from such everyday ingredients as porridge and tonic water.
