The seventh ""Brogeen"" story, this recounts how the leprechaun and his magical entourage come to the aid of two troubled children who leave their home in Dublin in search of their parents. Vascillating from the real world of Patrick and Judy to the illusory realm of the leprechaun, the plot follows a winding course. With no way of crossing the Irish Sea, Patrick and Judy are spirited away to Scotland on the ""wings"" of Brogeen and Trud (his elephant companion). To their great surprise the Edinburgh of their adventure is the historic land of Mary, Queen of Scots. It is the land to which Lorcan Barry, the children's father, had come to find work. In their relentless search, Patrick and Judy are separated, but re-united, the lovely queen lends her support and the children get a glimpse of an exciting kingdom. Eventually the family comes together and Brogeen and his team fly off, mission successfully accomplished. The earthy Irish leprechaun and his spirited cast of characters make up for some of the shortcomings in the story, the most serious of which are the many distracting side-plots.
