Standing by the Wall

Here in Slough House, the intelligence service's home for inept spies, it's beginning to feel a lot like Christmas. Roddy Ho is used to being the one the slow horses turn to when they need miracles performed, and he's always been Jackson Lamb's Number Two. So when Lamb has a photograph that needs doctoring, it's Ho he entrusts with the task. Christmas is a time for memories, but Lamb doesn't do memories - or so he says. But what is it about the photo that makes him want to alter it? How would the slow horses cope if Roddy Ho didn't exist? And most importantly of all, are the team having Christmas drinks, and if so, where? 'Standing by the Wall' offers a glimpse into the kind of seasonal merriment you might expect at Slough House, where the boss generally marks the festive season with an increase in hostilities.
