Doctor Who: The Death Pit (Time Trips) [EPUB ebook] 

Something odd is going on at the Fetch Brothers Golf Spa Hotel. Receptionist Bryony Mailer has noticed a definite tendency towards disappearance amongst the guests. She s tried talking to the manager, she s even tried talking to the owner who lives in one of the best cottages in the grounds, but to no avail. And then a tall, loping remarkably energetic guest (wearing a fetching scarf and floppy hat) appears. The Fourth Doctor thinks he s in Chicago. He knows he s in 1978. And he also knows that if he doesn t do something very clever very soon, matters will get very, very out of hand.
