It wasn't the first time I had escaped from a museum in an unconventional way. But never had it required Nato's assistance. To understand the predicament, however, first requires some sense of how I move through museums.
I can do the Louvre in under an hour, my pace guided by all that I am not particularly interested in. I will happily skip British Museum altogether, considering I have been to many of the places from which it looted artefacts.
