In December 1900, the lighthouse on Eilean Mor in the Flannan Isles, which had only been lit for the first time a year previously, was discovered deserted by its three keepers; their dinner table had been set with cold meat, pickles and potatoes, and a chair was overturned in an obvious urgent departure.  Two sets of oilskins and seaboots were missing, and otherwise the quarters and lamp were in perfect order.
