A simple courier job – take package across New York in a cab and deliver it.
However, it’s a New York post-alien visitation, with strange Pafs to be negotiated, talking dogs, and dinosaurs. Worse still, the slightly untrustworthy courier gets a sight of what is in the package he’s carrying (think Arnold Schwarzenneger removing the tracking device through his nose in ‘Total Recall’ only much worse, and organic). However, he doesn’t make life easier for himself by deciding to save the cab fare he’s given, and going by public transport.
It’s a well observed story, with a likeably incompetent protagonist, in the same milieu as Lees’ ‘The Corner of the Circle’ from Interzone #218.
