The Marquis Mazzini had one son and two daughters by his first amiable consort, supposed to be long dead when the story opens. The son is the original of Henry Tilney in "Northanger Abbey," and in General Tilney does Catherine Morland recognise a modern Marquis of Mazzini. But the Marquis's wife, to be sure, is _not_ dead; like the first Mrs. Rochester she is concealed about the back premises, and, as in "Jane Eyre," it is her movements, and those of her gaolers, that produce mystery, and make the reader suppose that "the place is haunted." It is, of course, only the mystery and the "machinery" of Mrs. Radcliffe that Miss Bronte adapted. These passages in "Jane Eyre" have been censured, but it is not easy to see how the novel could do without them. Mrs. Radcliffe's tale entirely depends on its machinery. Her wicked Marquis, having secretly immured Number One, has now a new and beautiful Number Two, whose character does not bear inspection. This domestic position, as Number Two, we know, was declined by the austere virtue of Jane Eyre. "Phenomena" begin in the first chapter of "A Sicilian Romance," mysterious lights wander about uninhabited parts of the castle, and are vainly investigated by young Ferdinand, son of the Marquis. This Hippolytus the Chaste, loved all in vain by the reigning Marchioness, is adored by, and adores, her stepdaughter, Julia. Jealousy and revenge are clearly indicated. But, in chasing mysterious lights and figures through mouldering towers, Ferdinand gets into the very undesirable position of David Balfour, when he climbs, in the dark, the broken turret stair in his uncle's house of Shaws (in "Kidnapped"). Here is a _fourth_ author indebted to Mrs. Radcliffe: her disciples are Miss Austen, Byron, Miss Bronte, and Mr. Louis Stevenson! Ferdinand "began the ascent. He had not proceeded very far, when the stones of a step which his foot had just quitted gave way, and, dragging with them those adjoining, formed a chasm in the staircase that terrified even Ferdinand, who was left tottering on the suspended half of the steps, in momentary expectation of falling to the bottom with the stone on which he rested. In the terror which this occasioned, he attempted to save himself by catching at a kind of beam which suspended over the stairs, when the lamp dropped from his hand, and he was left in total darkness." Can anything be more "amazing horrid," above all as there are mysterious figures in and about the tower? Mrs. Radcliffe's lamps always fall, or are blown out, in the nick of time, an expedient already used by Clara Reeve in that very mild but once popular ghost story, "The Old English Baron" (1777). All authors have such favourite devices, and I wonder how many fights Mr. Stanley Weyman's heroes have fought, from the cellar to their favourite tilting ground, the roof of a strange house!
