My second book was the lowdown about debt collection. The Debt Book. Encouraged by the look of that fat volume, or by some evil spirit, I got the idea of writing a book about Perth, Australia. That took months, an hour here, an hour there. The rest of the book will never be written.

When our clients started using the internet, I found myself suggesting encryption systems that could be relied on. Few clients had any ideas on the subject themselves. I use the Survey to help people understand the background and what they're doing when they encrypt and decrypt messages. The Western Australian Department of Commerce and Trade saw my encryption paper and asked me to write an article for them about internet security for business people. It covers email, FTP, ICQ, virtual private networks, and websites.
