All that they had

How very true. When the old HQ was sold by the philandering crook to the Lithuanian oligarch it was of course necessary to relocate the memorial to the members of staff who'd died in service in the two 20th century wars. And here it is.
Of course, the old organisation had survived much longer than that. It had even survived the occupation of Edinburgh by the Jacobite army: in those days, the treasurer had to negotiate his way through the lines to the castle to do his daily business. I guess these days that would be delegated. I wonder if John Campbell even had that as one of his key result areas.
