A 3-disc DVD set containing all 10 episodes of Houdini & Doyle Season 1 is released today in the UK. The full series has already aired in the UK on ITV Encore. It's currently showing in the U.S. on FOX.
This Region 2 DVD will not play on U.S. players. But I expect we'll be getting a DVD release here in the U.S. as well.
