About this book

Felix and his friend Isaac are mystery-mad, so when they find a strange, ancient coin buried deep in a plant pot, they have to investigate what it is and who put it there. 

The lucky jade money plant was in Felix’s family takeaway before being knocked over and damaged, so all the customers are suspects. Felix is desperate to stop any bad luck happening to his family, but unfortunately it looks like they’ll have to team up with Nina Dong, his sworn enemy, to solve this mystery. 

Can the newly formed Lucky House Detective Agency uncover the truth – and what links this seaside town to Hong Kong? 

At the heart of this cosy detective story is a strong friendship between Felix and Isaac that is heartwarming to read. Felix leads Isaac into some significant peril – not to be recreated at home – and they do fall out, but ultimately, they value each other too highly not to be friends again. 

The community of regular takeaway customers and Felix and Isaac's caring parents add to the heartwarming feel of this story, which nevertheless does still contain action and tension. The black and white illustrations add drama, too.
