In which Henry Tibbett, now a full Superintendent, moves into the rarified atmosphere of international politics, following up the mysterious death of a small-time gambler in a seedy British pub. And in which an equally astute and gentle policeman. Inspector Van der Valk (see Nicolas Freeling) of Holland, first encounters the redoubtable Superintendent from New Scotland Yard.
