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 Ballinalud. Suddenly there are old people acting strangely all over suburbia, 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 Os to solve the mystery, preferably before dinnertime.

The Secret Scientist is the third accidental adventure for Onion O’Brien and his gang of friends, the Five Os. This hilarious story from the zany brain of one of Ireland’s greatest funny men will be adored by all kids with a zest for fun.

‘A hilariously funny Scooby-Doo-esque romp in small-town Ireland brilliantly captured in Oisín McGann’s illustrations.’ Children’s Books Ireland

‘Byrne’s comedic touch, coupled with Oisín McGann’s quirky illustrations, give Onion O’Brien’s adventures a refreshing vitality as the gang lurches from one calamity to the next. Though our affinity with Onion in particular grows throughout the series, readers can dive straight into the action at book three and still feel part of the misfit gang.’ Pet O’Connell, The Evening Echo
