Bulgarian Umbrella (Signature Weapon)

This post is part of my Signature Weapons series. While most of the weapons mentioned so far are either traditional weapons and/or belong to crime fiction, this one is fairly modern and was made infamous during the Cold War. You may never have heard the term Bulgarian umbrella, but I think you probably know the device: a seemingly mundane umbrella with a hidden mechanism capable of shooting ricin in a victim's body. It has been used in real life by the Bulgarian ecret Services against dissidents. It's a signature weapon in the truest sense, the literal sense. Because of its origins, it belongs more to spy thriller than crime fiction, at least it's a more natural fit, but who knows, sometimes both genres connect. Obviously (and naturally), this is a villain's weapon.
