The detective’s role is simple: to catch the culprit. Yet behind each casual observation lies a learned mind, trained on finding the key to the mystery. Crimes, whatever their form, are often best solved through deliberations of logic – preferably amid complicated gadgetry and a pile of hefty scientific volumes. The detectives in this collection are masters of scientific deduction, whether they are identifying the perpetrator from a single scrap of fabric, or picking out the poison from a sinister line-up. Containing stories by R Austin Freeman, J J Connington and the master of logical reasoning, Arthur Conan Doyle, The Measure of Malice collects tales of rational thinking to prove the power of the human brain over villainous deeds.
