That all changed once Danny came out to meet me. After chit chatting for a few minutes, he took me to a small room – no wider than my outstretched arms – at the far end of which stood one of those classic red English phone booths. We stepped inside – a bit cramped – and Danny lifted the receiver and dictated a passphrase of some sort. Presto – the rear wall of the booth opened, and we stepped into – nerdvana.
