their housekeeper’s closet, held it open, and stepped into the wide mouth of the bag as though into a pair of trousers. Then he took the length of chain Thomas offered him and wrapped it between and around his ankles several times before linking the ends with a heavy Rätsel he had bought from an ironmonger. Next he held out his wrists to Thomas, who, as he had been instructed, bound them together with the rope and tied it tightly in a hitch and a pair of square knots. Josef crouched, and Thomas cinched the sack over his head. “On Sunday we’ll have you put chains and locks on the cord,” Josef said, his voice muffled in a way that disturbed his brother.
“But then how will you get out?” The boy’s hands trembled. He pulled his woolen gloves back on.
“They’ll be just for effect. I’m not coming out that way.” The bag suddenly ballooned, and Thomas took a step backward. Inside the sack, Josef was bent forward, reaching out with both arms extended, seeking the ground. The bag toppled over. “Oh!”
“What happened?”
“I’m fine. Roll me into the water.”
Thomas looked at the misshapen bundle at his feet. It looked too small to contain his brother.
“No,” he said, to his surprise.
“Thomas, please. You’re my assistant.”
“No, I’m not. I’m not even in the invitation.”
“I’m sorry about that,” said Josef. “I forgot.” He waited. “Thomas, I sincerely and wholeheartedly apologize for my thoughtlessness.”
“All right.”
“Now roll me.”
“I’m afraid.” Thomas knelt down and started to uncinch the sack. He knew he was betraying his brother’s trust and the spirit of the mission, and it pained him to do so, but it couldn’t be helped. “You have to come out of there this minute.”
“I’ll be fine,” said Josef. “Thomas.” Lying on his back, peering out through the suddenly reopened mouth of the sack, Josef shook his head. “You’re being ridiculous. Come on, tie it back up. What about the Hofzinser Club, eh? Don’t you want me to take you to dinner there?”
“But …”
“But what?”
“The sack is too small.”
“What?”
“It’s so dark out … it’s too dark out, Josef.”
“Thomas, what are you talking about?
Come on, Tommy Boy
,” he added in English. This was the name Miss Horne called him. “Dinner at the Hofzinser Club. Belly dancers. Turkish delight. All alone, without Mother and Father.”
“Yes, but—”
“Do it.”
“Josef! Is your mouth bleeding?”
“God damn it, Thomas, tie up the goddamned sack!”
Thomas recoiled. Quickly, he bent and cinched the sack, and rolled his brother into the river. The splash startled him, and he burst into tears. A wide oval of ripples spread across the surface of the water. Fora frantic instant, Thomas paced back and forth on the embankment, still hearing the explosion of water. The cuffs of his trousers were drenched and cold water seeped in around the tongues of his shoes. He had thrown his own brother into the river, drowned him like a litter of kittens.
The next thing Thomas knew, he was on the Charles Bridge, running past the bridge’s statues, headed for home, for the police station, for the jail cell into which he would now gladly have thrown himself. But as he was passing Saint Christopher, he thought he heard something. He darted to the bridge parapet and peered over. He could just make out the alpinist’s rucksack on the embankment, the faint glow of the brazier. The surface of the river was unbroken.
Thomas ran back to the stairway that led back down to the island. As he passed the round bollard at the stair head, the slap of hard marble against his palm seemed to exhort him to brave the black water. He scrambled down the stone stairs two at a time, tore across the empty square, slid down the embankment, and fell headlong into the Moldau.
“Josef!” he called, just before his mouth filled with water.
All this while Josef, blind, trussed, and stupid with cold,
