Fans of the previous books in The Great Mistake Mysteries series will be happy to reunite with dog walking detectives, Stephen and Renée, who are back in this fourth instalment (along with their favourite four-legged clients, Ping and Pong). Thanks to McNicoll’s narrative style, middle grade readers will identify with realistic dialogue and Stephen’s tendency to question everything and everyone around him... The real appeal of this novel is the humour and honesty of its likeable main character.
