Book five, and the Three Investigators are not only witness to a jewel theft, but sent a mystery by Alfred Hitchcock - to investigate gnome sightings in California.
I remember the cover image from reading this book in my school library, but the plot as I re-read it as an adult didn't ring any bells, and it was great to read a story in the series again without knowing where it was going.
The action is plausible, and the plot believable, which I always think is a bonus in a children's book - it shows that mysteries can be solved with the application of a little brain power and that the supernatural normally has an explanation (in fact, this one reminded me a little of Scooby Doo in that respect).
An excellent mystery which I've really enjoyed.
