My Friend Percy and the Sheik

What should you give a real sheik for dinner? And will Ulf mange to hypnotize Marianne so that she'll kiss him? Ulf is quite an ordinary boy, growing up in a suburb in Sweden. But when his father, an amateur show wave radio fan, 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 move.
