I thought this Sixties Christmas card from Cornell Woolrich to his friend Don Yates (pictured below) was very characteristic of the moody author in its calculated sense of ambiguity. On the plus side, from most of the sad accounts of Woolrich's life, you'd be surprised to learn that he even owned Christmas cards and actually took the time to send them to people.
But let me assure all readers of The Passing Tramp that I always miss you when you're not here! Unless you only ever comment about typos. ;)
Merry Christmas and/or Happy Holidays to you all. And may there be many mysteries in your futures.
