THE STORY GRIPS the readers right from the start. The secret letter makes the reader enough curious to know what is store in next ? The Professor is an interesting character and moves the plot further. The funny situations tickle the readers and reveals the other side of the characters.The author has again created curiosity at the end when the oyster is being carried to another place for safety reasons. I recommend this series not only for children but adults can also enjoy reading it.The author has successfully created suspense, drama, wit, humour, thrill in the story. MY RATING:- 4.75/5
