Starring Katy Manning as both Jo Grant and Iris Wildthyme, this classic Companion Chronicle find the Third Doctor's faithful friend trapped by a mysterious alien...

Christmas 2010, and Jo Grant finds herself stuck in a department store elevator with an alien creature called Huxley. 

Huxley is a narrator from Verbatim Six, and he is here to let Jo revisit the best time of her life – when she was the plucky companion to that eccentric Space/Time traveller known only as... Iris Wildthyme.

Confronted with memories she knew nothing about, Jo agrees to a meeting with Iris inside her transdimensional bus, and together the three of them take a trip back in time. Back to the 1970s, to UNIT HQ, and a meeting with the only person who knows the whole truth...

Written by Ms. Wildthyme's creator Paul Magrs, this brilliant story is the perfect crash course for those new to the eccentric adventuress.
