Ask for help.
Being a consulting detective means you need to be an expert in many things. But you can’t know everything, which is why it’s important to cultivate a network of experts to lend a hand when needed. This means cultivating your own network of irregulars, from mathematicians to geologists to a hacker collective who can offer the expertise you need when you need it. If you’re lucky, your experts will be happy to help for the intellectual challenge of it.
