Picks & Shovels (Martin Hench #3) by Cory Doctorow; 2025. Hardcover.

The year is 1986. The city is San Francisco. Here, Martin Hench will invent the forensic accountant--what a bounty hunter is to people, he is to money--but for now he's an MIT dropout odd-jobbing his way around a city still reeling from the invention of a revolutionary new technology that will change everything about crime forever, one we now take completely for granted.

When Marty finds himself hired by Silicon Valley PC startup the Three Wise Men to investigate a group of disgruntled ex-employees who've founded a competitor startup, he quickly realizes he's on the wrong side. Marty ditches the greasy old guys running Three Wise Men without a second thought, utterly infatuated with the electric atmosphere of Magenta Women's Enterprise. Located in the heart of the Mission, this group of brilliant young women found themselves exhausted by the predatory business practices of Three Wise Men and set out to beat them at their own game, making better computers and driving Three Wise Men out of business. But this optimistic startup, fueled by young love and California-style burritos, has no idea the depth of the evil they're seeking to unroot or the risks they run.

In this company-eat-company city, Martin and his friends will be lucky to escape with their lives.
