Now Nell did detection from Tuesday till Sunday,
But did something totally different each Monday.
She found Peter's bag and she tracked down her lead,
Then set off for school, where she heard children read.
The children loved reading their stories to Nell,
And Nell loved to listen - and also to smell.
Sniff, sniff, sniff! Mixed in the air
Were plasticine, custard, and newly washed hair,
The crusts in the bins and the coats on the hooks,
But the best smell of all was the smell of the books.
