In 1867 Charles Dickens and Wilkie Collins collaborated to produce a stage play titled No Thoroughfare: A Drama: In Five Acts. Two boys from the Foundling Hospital are given the same name, (Walter Wilding), with disastrous consequences in adult-hood. After the death of one – now a proprietor of a wine merchant’s company – the executors, to right the wrong, are commissioned to find a missing heir. Their quest takes them from wine cellars in the City of London to the sunshine of the Mediterranean – across the Alps in winter. Danger and treachery would prevail were it not for the courage of the heroine, Marguerite, and a faithful company servant.
