“But you go to church, to a Lenten service—?” It was as if he had known her for years, and their unconventional behaviour never crossed his mind.  He did not even ask himself where they were moving.

“I go to church to rest my nerves—­as do many other people,” she replied; “I was interested in the parallel of the Seven Deadly Sins and the Seven Deadly Arts.”

“You believe the arts are sinful?” He was curious.

“I don’t believe in sin at all.  A bad conscience is the result of poor digestion.  Sins are created so that we pay the poll-tax to eternity—­pay it on this side of the ferry.  Yet the arts may become dangerous engines of destruction if wrongfully employed.  The Fathers of the early Church, Ambrose and the rest, were right in viewing them suspiciously.”—­He spoke:—­

“The arts diabolic!  Then what of the particular form of wizardry practised so successfully by the celebrated Mrs. Whistler, one of whose names is, according to the Talmud, that of Adam’s first wife?”

“What do you know, my dear young man, of diabolic arts?”

“Only that I am walking with you near the park on a dark night of April and I never saw you before a half-hour ago.  Isn’t that magic—­white, not black?”

“Pray do not mock magic, either white or black.  Remember the fate of the serpents manufactured by Pharaoh’s magicians.  They were, need I tell you, speedily devoured by the serpents of Moses and Aaron.  Both parties did not play fair in the game.  If it was black magic to transform a rod into a snake on the part of Pharaoh’s conjurers, was it any less reprehensible for the Hebrew magicians to play the same trick?  It was prestidigitation for all concerned—­only the side of the children of Israel was espoused in the recital.  Therefore, do not talk of black or white magic.  There is only one true magic.  And it is not slate-writing, toe-joint snapping, fortune-telling, or the vending of charms.  Magic, too, is an art—­like other arts.  This is forgotten by the majority of its practitioners.  Hence the sordid vulgarity of the average mind-reader and humbugging spiritualist of the dark-chamber seance.  Besides, the study of the super-normal mind tells us of the mind in health—­nature is shy in revealing her secrets.”

They passed the lake and were turning toward the east driveway.  Suddenly she stopped and under the faint starlight regarded her companion earnestly.  He had not been without adventures in his career—­Paris always provided them in plenty; but this encounter with a homely woman piqued him.  Her eye he felt was upon him and her voice soothing.
