"When a crime needs solving, there's only one dog for the job! Join Nell the Detective and help solve the mystery of the missing books. There once was a dog with a keen sense of smell. She was known far and wide as Detective Dog Nell. Peter's dog Nell has an amazing sense of smell. Her ever-sniffing nose is always hard at work solving mysteries and finding all Peter's lost toys. But Nell has other talents too . . . When she's not cracking cases, Nell goes to school with Peter and listens to the children read. Books about dinosaurs, books about space and even books about dogs - Nell loves them all! But one day Peter and Nell arrive at school to find all the books have disappeared! Who could have taken them, and why? Luckily, Detective Dog Nell, with help from the whole class, is ready to sniff out the thief! Written by Julia Donaldson and illustrated by the multi-talented illustrator and print-maker Sara Ogilvie, The Detective Dog is a fast-paced celebration of books, reading, libraries and the relationship between a little boy and his rather special dog."
