Neil Gaiman's 'Doctor Who' Script Found In A Cab, Returned

Neil Gaiman left the script to his upcoming "Doctor Who" Season 7 episode in a cab, but no spoilers about the Cybermen or the Doctor's companion were revealed thanks to the woman who found it.

According to WalesOnline, Hannah Durham found the script to "The Last Cyberman" in a taxi on Halloween night, but wasn't aware of the TV gold she had stumbled upon.

"I glanced at it enough to see that it was a script and I saw the title and everything, but I didn’t feel the urge to read through it or copy it or anything," she said.

With the help of a friend, Durham said she contacted "Doctor Who" writers and producers and returned the script. Gaiman took to Twitter to thank Durham.

Gaiman's "Doctor Who" episode will air later in Season 7 and will feature guest stars Warwick Davis, Tamzin Outhwaite and Jason Watkins as "misfits on a mysterious planet."

"Cybermen were always the monsters that scared me the most! Not just because they were an awesome military force, but because sometimes they could be sleek and silver and right behind you without you even knowing," Steven Moffat, "Doctor Who" lead writer and executive producer, told BBC. "And with one of the all-time classic monsters returning, and a script from one of our finest novelists, it's no surprise we have attracted such stellar names as Tamzin, Jason and Warwick."
