My Friend Percy and the Sheik by Ulf Stark
What should you give a real sheik for dinner? And will Ulf manage to hypnotize Marianne so she'll kiss him? Ulf is an ordinary boy, growing up in a quiet suburb. But when his amateur radio fan father invites a real sheik to dinner, his mother gets nervous. Ulf is worried that something far worse will happen-that Percy, his best friend, will have to leave town. My friend Percy and the sheik is the second in a series of three books about Ulf and Percy.
