Dominoes 2: Lord Arthur, Savile's Crime and Other Stories

The three stories in this book are about ordinary people, people like you and me; but they find themselves in surprising situations. Lord Arthur Savile, a rich man with no enemies, finds out that he must do something terrible before he can marry. Poor young Hughie Erskine gives money to an old beggar but the beggar is not what he seems.
And Lord Murchison falls in love with a mystery woman but what is the strange secret behind the door in Cumnor Street?
