boot.
âThelmaâs at home,â she went on. âGrant told me. And I checked the phone book, so now I know where she livesâ¦â
She was beginning to sound like one of those scary stalkers you read about.
âFantastic,â I said sarcastically. âWell, as soon as Iâve had my shower, Iâll go round there and tell her Iâm her guardian angel, ready to save the day â and stop her killing her ex-boyfriend.â
Gaby scowled. âYou canât do that!â she snapped. âBut maybe we could go round there together and sort of keep a lookout. Make sure she isnât up to anything.â
â
We
?â I said.
âWell, two of us wonât look so suspicious. No offence, Billy, but if I saw you hanging around outside my house, I think Iâd call someone.â
She sort of had a point. I sighed. I wished I had an excuse not to go. But I didnât. Dad had been called out on an emergency plumbing job in the early hours and was now snoozing it off. I was surplus to requirements.
âI suppose youâd better come in,â I said.
While I got dressed, Gaby scribbled her auntâs number on a piece of (pink) paper, which I gave to my mum, along with a cock-and-bull story about going around to Gabyâs with a gang of kids from school to watch a DVD.
Mum smirked a strange smirk that I hadnât seen before. And, annoyingly, I felt my face turn red. I grabbed my coat and escaped.
âHave you got your tool bag?â asked Gaby.
âWhy?â
âBecause it might come in handy â you know, a cover for why we might be in Thelmaâs neighbourhood. You could pretend youâre doing a plumbing job.â
I stared at her. My tool bag weighed a ton. There was no way I wanted to lug it around. But then again, I might actually feel safer around Thelma if I had several heavy tools within reach. A few moments later, I reappeared with my bag. And we were off.
Gaby was smaller than me (which is saying something), but she was much faster. It was like going for a walk with a whippet. She powered alongside me, every so often getting so far ahead sheâd have to stop and wait. It was actually quite annoying. Then, suddenly, she stopped.
âThis is it,â she said, peering at a bit of (pink) paper. âNumber four â the big house over there.â
Thereâs obviously a lot of dosh in pies, because weâd arrived at a pretty posh neighbourhood. The cars were all shiny and new, and the gardens were stuffed full of those adventure play centres that only truly rich kids own. Some of them were bigger than my house.
âLetâs take a closer look,â whispered Gaby. She grabbed my arm and we went towards the house.
But a moment later, she suddenly shoved me sideways, really hard. (For someone so small she had iron-man arms.) We landed in a thorny bush.
âOWWWWWWWWWW!â I screamed, or I would have done, if Gaby hadnât clamped her small, sweaty hand over my mouth.
âI think sheâs coming,â she whispered.
I wriggled a bit. It was hard not to with a giant thorn stuck in my behind.
Gaby pinched my arm. âSsh!â
And then I saw her. It was Thelma all right. She was walking briskly down the road, pulling one of those old-lady shopping trolleys behind her, and she had a determined look on her face.
Chapter 10
I felt my heart pounding, and I wondered whether it was from fear of Thelma, or the fact that I was struggling to breathe with Gabyâs hand over my face.
A few moments later, Gaby let go, and I collapsed back onto the pavement.
âDonât ever do that again!â I yowled.
But Gaby wasnât listening. âCome on, sheâs getting on that bus.â
Thelma had reached the end of the street, and as if by magic, a bus had just appeared.
âWe canât follow her,â I gasped, as Gaby dragged me towards the bus stop. âSheâll recognise
