days, I donât know,â Rose said. She reached into her pocket, to make the point. Her phone wasnât there.
âItâs probably for daft people who leave their phones at their mumâs,â said the Doctor, still staring at the poster. âCome on, weâre going into town.â
âWhy?â
âMonstrithology. I want to find out how itâs possible for a human to fit inside a costume like that. See the wrists? And the knees? Iâd have said it couldnât be done.â
Rose almost jumped into the air. âSo itâs aliens? Aliens taking over the planet via shopping?â
The Doctor shrugged. âDonât have to be trying to take over the planet, just cos theyâre aliens. Iâm not trying to take over the planet. The Cookie Monster isnât trying to take over the planet. Well, not the bits which donât involve cookies.â
She gave him a look. âCookie Monster is a puppet.â
He just smiled knowingly.
âHeâs got someoneâs hand up him and some bloke does his voice!â
The Doctor smiled again. âYou humans are so gullible.â
âYou mean heâs really an alien? Cookie Monster?â
Now the Doctor laughed. âYou humans are so gullible!â
A bus was drawing up to the kerb just ahead. The Doctor grabbed Roseâs hand and they ran for it, leaping on just as it was pulling away again. The driver glared at them, especially when he found out the Doctor actually wanted to pay money for a ticket. He didnât notice that the travel card Rose waved at him had run out a year before.
âIâm such a criminal,â she said, swinging into a seat.
âYeah, well, donât expect me to pay your bail,â the Doctor replied.
âSo, are they really aliens?â she whispered, leaning in close so the nosy old biddies in the seat in front couldnât hear. Theyâd given Rose and the Doctor disapproving looks as theyâd jumped on board; Rose wasnât sure if it was because the bus had already been moving or because they thought the Doctor was âold enough to be her fatherâ and didnât think much of that. Probably the latter. She felt like shouting at them, âSo, how dâyou know heâs not my father then?â
âI donât know,â he answered. âMight be. Probably just a dodgy picture, Photoshop or something.â
âOh,â she said. âThat seems like cheating, somehow. Anyway, where are we going?â
âBit of shopping, bit of monster spotting . . .â
âJust in case?â
âJust in case.â
The Percy Porcupine booth was right slap bang in the middle of the high street, covered in posters. âI wonder if aliens bother with getting planning permission,â said Rose. âThat could be a clue.â
There was a little queue outside the booth, a couple of people, tickets in hand. The Doctor and Rose joined the line, and watched the winners hold up their tickets to a little panel with a red light on it. The light went green as the first person was bleeped into the booth, and the door slid closed behind them. The light turned red again.
âPretty elaborate security for a lottery thing,â Rose said. âOr maybe they just donât want people stealing the prizes. Or theyâre expecting the games consoles to break down and donât want to have to deal with a load of irate computer geeks.â
âAnyway, looks like you need a winning card to get in,â said the Doctor. âItâs like Charlie and the Chocolate Factory all over again.â
The first man came out, a boxed-up games console in hand. The door slid back decisively behind him. The second queuer, a woman, held up her ticket. The Doctor and Rose sidled close, and the woman frowned. âExcuse us,â said the Doctor, giving her a charming smile, âwe just wanna . . .â
But sheâd nipped
