Masterson spoke crisply, now. "Suppose I tell you that Payson has confessed that he has a son?" He shifted his cigar in his mouth and watched the bolt fall.

As the words came out, Granthope's face, which had shown only a contemptuous, bored expression, changed instantaneously. It was, for a moment, as if a sponge had been passed over it, obliterating all signs of intelligence, leaving it to blank, hopeless bewilderment. Then his mind leaped to its inevitable conclusion, the whole thing came to him in a sudden revelation; a dozen unnoticed details jumped together to form the pattern, and there it was, a problem solved: horror and despair. He was Clytie's half-brother! He sat enthralled by it for a moment—he forgot the leering scoundrel in front of him—he saw only Clytie—inaccessible for ever.

Then, still without a word, he rose like one in a dream, sought for his hat, went out the door, and ran down-stairs. As in a dream, too, Masterson's astonished, entreating, indignant exclamations followed him, echoing down the hall. Granthope paid no attention, he had no thought but for Clytie—to see her immediately, at any cost.

He swung aboard an O'Farrell Street car, found a seat in the corner of the open "dummy" portion, and strove with the tumult in his soul. The torturing thought of Clytie for ever lost to him coiled and uncoiled like a serpent. He did not doubt Masterson's revelation, nor could he doubt its obvious interpretation in the light of the many revelations that had been cast upon Mr. Payson's past. Yet it must be corroborated before he could wholly abandon himself to renunciation. He tried to keep from hoping.

He was Clytie's half-brother! His mind wrestled with it.

The car filled at the Orpheum Theater, taking on a load of merry passengers, who crowded the seats inside and out till the aisles and footboards were packed. The bell clanged as they drove through the Tenderloin, rolled round the curve into Jones Street and took the steep hill, climbing without slackening speed. It rounded two more corners, wheels creaking; and as it passed, the broad area of the Mission and South San Francisco was for a moment revealed in the gap of Hyde Street, a valley of darkness, far below, gorgeously set out with lights, like strings and patterns of jewels. At California Street a crowd of passengers, mostly Jews, overdressed, prosperous, exuberant, transferred for the Western Addition. The car went up and up, reached the summit and coasted down the dip to Pacific Street. Another rise to Union Street, where another line transferred more passengers towards the Presidio. Then, with only one or two inside, and the conductor lazily picking his teeth on the back platform, they climbed again up to the reservoir. Here a long incline fell giddily to the water and the North Beach. The car rolled to the crest, ducked fearfully, and boldly descended the slope.

He was Clytie's half-brother! The thought of it was darker than the night about him.

Ahead, the black stretch of water, the flash of the light on Alcatraz, and a misty constellation in the direction of Sausalito. To the left, a huge shoulder of Russian Hill swept back from the northern harbor in a wave toward the south. It was sprinkled with artificial stars—the gas-lamps, electric lights, and illuminated windows of the town. One street, directly opposite, was a line of topaz brilliants, loosely strung, scattering over the hill. Fort Point light, two miles away, flared alternately a dash of pale yellow—and short pin-pricks of red. Farther away, Point Bonita was flaming, regular as a clock, a periodic spasm of diamond radiance. Electric cars, like lighted lanterns, were painfully climbing the Fillmore Street hill. All about was a sparse settlement of wooden houses, thickening as it rose to the palaces of Pacific Avenue crowning the summit. A dark space of grass and trees lay ahead—the Black Point Military Reservation—the bugles were calling through the night.

It was past eleven o'clock when Granthope ran up the steps into the Paysons' front garden, walked rapidly up the path and stood for a moment outside the door. There was a light in Clytie's workroom; he threw a handful of gravel against the pane, and waited.

The curtain was drawn aside, the window raised, and Clytie looked out boldly. She saw him, waved her hand, and disappeared. A few moments later she opened the front door quietly. She wore a soft, clinging, blue silk peignoir; her arms were half bare, and her tawny hair was braided for the night. She came out with a look of alarm.
