I’ve spent a considerable amount of time researching 19th and 20th-century private detectives, both for my Substack on the subject, and for my next book. One of the agencies that has come up time and time again in my research is Arrow’s – described in the press as one of the largest detective agencies in Europe. Arrow’s Detective Agency was established at Rolls Chambers, 89 Chancery Lane, in London, by two former police detectives. Charles Arrow was the man who gave his name to the agency, but he established it in partnership with his former colleague, Henry Derby.
