Amiable architect John Assael has an identical twin brother.
Honestly, he does. Astragal now knows he is Robin - a lawyerturned-developer with a similarly fluffy little beard.
However this information didn't come easily. For a long time a sceptical Astragal was convinced the whole affair was a very cunning ruse. In fact it was not until Robin pulled out his credit card - under duress - that it all began to make sense.
Even then, it was only when they were spotted together Astragal was finally won over. Another double, please.
