Drake's will was the focus of a vast confidence scheme which Oscar Hartzell perpetrated in the 1920s and 1930s. He convinced thousands of people, mostly in the American Midwest, that Drake's fortune was being held by the British government, and had compounded to a huge amount. If their last name was Drake they might be eligible for a share if they paid Hartzell to be their agent. The swindle continued until a copy of Drake's will was brought to Hartzell's mail fraud trial and he was convicted and imprisoned.
