Mr. Jack Stapleton

Mr. Jack Stapleton is the true antagonist of the Sherlock Holmes novel known as The Hound Of The Baskervilles and was originally a rather innocnet-looking former schoolmaster found of chasing butterflies on the moors and pursuing antiquarian interests. Jack is a polite Victorian gentleman on the exterior but this hides a hot temper which reveals itself at key moments. It transpires later in the story that Stapleton—in reality a long-lost relative of Sir Henry's who stands to inherit the Baskerville fortune—is a scheming, manipulative and money-hungry criminal that Holmes and Watson come to respect and fear.
