David McKittrick: Peace is undermined by scandal on a grand scale
The lock-keeper's cottage is a calm, quiet spot beside the River Lagan on the peaceful green southern outskirts of Belfast, close to two little bridges where the meandering river meets an old canal.
Derelict for half a century, it has been restored in recent years as a modern refreshment halt where strollers, joggers, cyclists and dog-walkers call in for coffee and scones. There is a fair bit of history in those parts: the Duke of Wellington used to canter round the adjoining estate.
But from now on it will probably be known locally as Robinson Cottage, for it was here that outspoken Iris Robinson, MP for Strangford, helped to set her teenage lover up in business.
