The Secret Scientist (Hardback original)

Onion and the gang are at it again. This time they've stumbled across a Russian scientist at an old folks' home, whose crazy experiments are causing all kinds of confusion in Ballinlud.

Suddenly there are old people acting strangely all over suburbia, with power cuts and People in Black (PIBs) menacing the locals.

Not even The Ferg and Judge, the local guards, can figure it out. It's up to the Five O's to solve the mystery, preferably before dinnertime!

This hilarious story from the zany brain of one of Ireland's greatest funnymen is the third accidental adventure for Onion O'Brien and his gang of friends, the Five O's.

The third book in the deadly new series from one of Ireland's best-loved comedians.
