Professor Michael Irwin, plodding through his obligatory academia-sheen intro to this edition, tells us that many Hardy novels can be identified from their first line alone. So it's gurt lush like that five out of the seven short stories here start with some reference to agricultural England, the south-west, meadows, ewes, cows, dairies, milkers, and a town (of the singular and non-bustling variety). Which is fair enough really, as Hardy's animus was his personal vision of the region he grew up and spent most of his life in; his Wessex, a Dorset of the past, worn away by the same inevitable forces of fate and time he sets up against all his most memorable characters.
In his General Preface to the Novels and Poems, Hardy described how one of his aims as a novelist was to "to preserve for my own satisfaction a fairly true record of a vanishing life", and his method seems surprisingly modern. In all the Wessex Tales he stresses his separation from the narrative by presenting it as a piece of local myth, a story passed on through the generations. All the tales are brought up from the past, "fifty years ago a lonely cottage stood...", adding to the dreamlike quality of Wessex, a place that never really exists but in the imagination of Hardy himself, but which you half expect to see popping out of local archives and museum daguerreotypes.
Some of the stories are linked directly to historic events of the early to mid 1800's; like the stationing of the King's guard's at Lyme Regis, and Napoleon's possible reconnoitring of the south coast. Some stories are pure drama, or even horror; The Withered Arm has a healthy macabre edge to it. The two major stories, novellas almost, Fellow-Townsmen and Interlopers at the Knap, are brilliant examples of Hardy's depiction of people at the whim of not only their own ineluctable fate, but also their own failures of character. People who fail to make that stand for their own, and because the blank universe itself will not intercede, fail to take what was there for them all along.
The Wessex Tales are a great introduction to Hardy's general themes, his naturalistic approach, and his questioning of late Victorian social morality. You can read any of them in a sitting and none of them disappoint. Can't ask for more than that.... except for maybe a happy ending here or there.
