10 Times Doctor Who Appeared In Other TV Shows
8. Sherlock
Considering that Sherlock was created by Steven Moffat (Doctor Who showrunner between 2010 - 2017) and Mark Gatiss (Doctor Who writer between 2005 - 2017), it would almost be a crime if it didn't contain any Whoniverse connections.
Fortunately then, it does!
In the Series 4 episode The Lying Detective, some incredibly attentive viewers noticed something unusual resting on the mantelpiece pictured above. Can you spot it? Just there, right behind the magnifying glass.
This probably flew over the heads of the vast majority of viewers, but for an in-the-loop minority, this was a really cool easter egg. That "T" symbol behind the magnifying glass is actually the logo of Torchwood, an organisation in the Doctor Who world that protects the Earth from alien threats.
There's many a fan theory that Sherlock and Doctor Who exist within the same universe (largely stemming from Moffat's involvement in both shows), and this only added more fuel to that fire.
