Saturday Matinee: The Hound of the Baskervilles

On History Daily, we do history, daily. Every weekday, host Lindsay Graham (American Scandal, American History Tellers) takes you back in time to explore a momentous event that happened ‘on this day’ in history. Whether it’s to remember the tragedy of December 7th, 1941, the day “that will live in infamy,” or to celebrate that 20th day in July, 1969, when mankind reached the moon, History Daily is there to tell you the true stories of the people and events that shaped our world—one day at a time. So if you’re stuck in traffic, bored at work—wherever you are, listen to History Daily to remind yourself that something incredible happened to make that day historic.
