Life is never dull when you own a computer... that talks!

Tom's life is fraught with problems. There's a series of thefts from his Dad's factory, his sister Marion's having problems with her love life and his bossy Aunt Gertrude has come to stay. To top it all, he and Emma must think up two brilliant fundraising ideas for the school trip to France.

Fortunately, that amazing machine Zenda comes up with some solutions but then, on the boat to France, a truly menacing mystery develops.
