Zola’s neighbours have lived at number ten Boomerang Street for a month now.

She is very curious about them.

‘My mum says there is no harm at all in being curious,’ she tells Alessandro.

With his help, Zola begins to collect some information.

There’s a girl named Bianca and a boy named Omar, as well as a mum and dad.

Do you know how she knows this?

Every morning, Zola hears the mum say, ‘Bianca, I’m waiting in the car!’

Every night Zola hears the dad say, ‘Omar, take the plates out of the dishwasher!’

Then the mum again. ‘Bianca, don’t let Tim Tam near Teta’s knitting.’

‘Who do you think Teta and Tim Tam are?’ Zola asks Alessandro on Tuesday after school.

They’re trying to catch a glimpse of their neighbours through a crack in the timber fence.

‘Maybe they have a baby brother and a big sister,’ Alessandro says.

Zola shakes her head. ‘I've seen their car. There are only four stick figures on their back window. One dad. One mum. One boy. One girl.’

Suddenly they hear a noise.

Zola is sure someone is on the other side of the fence lurking in the leaves.

Gigi barks with great excitement.

Monty is being a bit more polite.

It sounds like this.
