Rosie Maldonne thought she hit it big when she stumbled upon an envelope of cash. But with a nasty flu keeping her laid out, school fees due and Christmas on the way, she finds herself back in the red. Time to find a real job. After weeks of searching, Rosie is losing hope when the man of her dreams happens to post a new position: cleaning for an elderly person. Perfect! She lands the job, but the new role brings more than the promise of romance.

When orphaned twins appear on her doorstep - desperate and on the run - Rosie agrees to hide them. Harbouring illegal immigrants and a diamond necklace stolen from the Mafia a year ago is stressful work. Paranoid and seeing suspicious people everywhere, Rosie contemplates fleeing to Amsterdam or seeking help from her new prince charming.

In this hilarious and suspenseful second investigation, Rosie has no choice but to roll up her sleeves and keep her ever-expanding family from harm.
