I am sending you a postcard which shows nine doors of various designs that can be found in the small town of Sandwich in Kent

One of the doors is the entrance to the house of the Widow Roberts

Does she still live at number sixty-two?

She has never lived at number sixty-two

Then advise me of her door so that I may visit her when I am next in the town

You will find the Widow Roberts if you ignore the first six doors and lay waste to the seventh

You talk in riddles my friend

Believe me the postcard is as good as any map and I know that the good widow will be very pleased to see you

Good luck and please note if you reach the ancient Barbican then you have travelled too far and will have to retrace your steps

On the morrow I will contact the Widow Roberts and advise her of your unusual visit
