It is now 2:30 AM in Helsinki. I’m have just raided the minibar, devouring a bag of almonds and downing a gin and tonic. CNN is playing on the TV. As much as I love traveling abroad to promote my books, this is the downside of hopping across the Atlantic — waking up fully alert hours before dawn, my inner clock telling me it’s time for dinner, and knowing that in six hours I will have to be at my best, looking bright-eyed and intelligent. Fat chance.
