When the statues of lions surrounding Nelson's Column in London's Trafalgar Square start roaring at passersby, Geronimo is contacted by secret agent 00K to travel to London to solve the mystery. He is glad to, because an old professor of his, Reginald Ratting, is giving a talk at the National Gallery, and Geronimo doesn't want him to be interrupted by the lions. Cousin Trap accompanies Geronimo, ostensibly to participate in a magic competition. While Trap doesn't do so well, and Geronimo has to come to his aid, the mystery of the roaring lions is solved so easily by our intrepid friend that we have to wonder if Scotland Yard was hanging out posh places having fancy cheese instead of investigating.
Geronimo frequently takes breaks from his journalism career to be a secret agent, but has apparently not completed the training, because he always runs into problems. Perhaps he should give up that gig and take on magic as a full time career-- he did much better at that than Trap did! Usually, this original series manages to intertwine two plots, and usually manages to involve Geronimo enjoying at least one sumptuous repast.
Reluctant readers or elementary students are usually the ones to pick these books up, and it's great when the books offer them a small glimpse of life in another country. My students are very much looking forward to the next volume of this, The Bollywood Burglary, and I'm interested to see how well Geronimo does in India!
