Behold, Here’s Poison is a good example of how difficult it must have been to investigate back in the 1920s. There were no CCTVs, camera phones, voice recognition, or DNA analysis. Even fingerprinting really just started in 1901. All the police had: post-mortem (never as sophisticated as forensics today), witnesses (mostly unreliable), and criminal psychology (quite dodgy). There’s also a certain disdain towards police among the upper classes, which makes it difficult to make honest inquiries.
That’s why Inspector Hannasyde and his very-chatty Sergeant Hemingway are in a bit of a pickle. Old Mr. Matthews has been poisoned by nicotine overdose, and his entire remaining family is suspect. Then his sister dies, also by nicotine poisoning, and the police none the wiser. The Inspector knows that Randall, the extremely snarky dandy heir to Matthews, is hiding something. But Randall just won’t spill the beans.
