Cyfrinach tywyll Llundain

Beth ydy cyfrinach dywyll Llundain?

London is a city few people understand, and those that are least likely to understand it are its residents and its proselytisers. The reason so few understand it is because hardly anyone knows that London possesses a deep, dark secret. It’s a secret I found out quite by chance in the mid-nineties, and have kept to myself ever since, largely because so few people I could tell it to would recognise it, and, even if they recognised it, would be prepared to ever admit it…

Dw i’n chwilfrydig iawn am y theori yn yr erthygl am Lundain yma. Darllena’r peth cyfan, bydd y gyfrinach yn dy ben am ddyddiau.
