My Moss Reid character is a private eye. When (or if) he gets paid, he prefers cash. Not to avoid tax, more in terms of client confidentiality. Imagine if a client’s bank statements had items marked “Wilde & Reid – Private Investigators”. Not great in, say, a case of a cheating spouse.
In real life, I get billed once a year by a “Detective/Protective Agency”. At least that’s how it appears in “Pending Activity” on my online banking account (see above). Once processed, it appears in my Visa Card statement and the mystery is resolved: it’s for my house alarm company.
You could have a lot of fun with bill statements in crime fiction…
