Young George Ferrier’s frivolous jaunt in London ends with an unexpected encounter with wealthy Mr. Green, old friend of his father, who spontaneously drafts George to be a trustee for his daughter Elma. George accepts (primarily due to the payment involved) and puts it out of his mind, returning home to his high-spirited Irish mother, distracted astronomer father, and friends Peter Seeley and his sister Cathy.
But Mr. Green’s sudden death, and the discovery that his fellow trustees are distinctly on the shady side, launches George into a series of rollicking adventures as he attempts to secure the overly-sheltered Elma’s wealth, protect her from fortune-hunters, and shield her from her own naïve instincts.
