Tulkinghorn is a little disturbed by this separated at birth (but believes it to be funny nevertheless).
Prompted by an anonymous tip-off, Tulkinghorn is led to believe that all is not what it seems at White & Case. Anyone standing too near the offices of intellectual property guru David Llewelyn might hear strange howling noises from above. Fans of the strange town of Royston Vasey might think it a strange coincidence that Tubbs (played by Steve Pemberton) has a son called David too. Just remember, White & Case is a local firm for local people, and most importantly don't touch the precious things.
