About the Author
Hartigan Browne, arguably Britain's greatest detective, has solved hundreds of complex crimes including robberies, murders, accidental deaths, fraud and at least one case of handling a salmon suspiciously. His success, however, means he is now overwhelmed with people requiring his help and cannot keep up with the demand for his services. A great believer that everyone has a brilliant mind, he is keen to mentor those who have the perseverance, resilience and curiosity that is required to join the Hartigan Browne Detective Agency.
