When he finally reached the bookcase on which Mrs. Babakov had said she’d hidden her husband’s work, he closed his eyes and prayed. He opened his eyes to find that Tess of the d’Urbervilles was no longer in its place; just a gap covered with a thin layer of dust between A Tale of Two Cities and Daniel Deronda. Mrs. Babakov had made no mention of Daniel Deronda.

He glanced back toward the counter, to see the old woman turning a page. Standing on tiptoe, he stretched up and eased A Tale of Two Cities off the top shelf, accompanied by a shower of dust that sprinkled down on him. When he opened it, he thought he might have a heart attack, because it was not a copy of Dickens’s work but a slim volume by Anatoly Babakov.

Not wishing to draw attention to his prize, he took two other novels from the same shelf, Greenmantle by John Buchan and Jamaica Inn by Daphne du Maurier, and pretended to browse as he made his way slowly toward the counter. He almost felt guilty interrupting the old woman as he placed the three books on the counter in front of her.

She opened each of them in turn and checked the prices. Mrs. Babakov had even penciled in the price. If she’d turned one more page, he would have been caught. She didn’t. Using her fingers as an adding machine, she said, “Eight rubles.”

Harry handed her two five-ruble notes, having been warned when he was in Moscow for the conference that shopkeepers had to report anyone who attempted to purchase goods with foreign currency and, more important, that they were to refuse the sale and confiscate the money. He thanked her as she handed him his change. By the time he left the shop, she’d turned another page.

“Back to the airport,” said Harry as he climbed into the waiting taxi. The driver looked surprised, but swung obediently around and set out on the return journey.

Harry opened the book once again to check that it hadn’t been an illusion. The thrill of the chase was replaced by a feeling of triumph. He turned to the first page and began reading. All those hours spent studying Russian were finally proving worthwhile. He turned the page.

An early evening traffic jam meant the journey back to the airport took far longer than he’d originally anticipated. He began to check his watch every few minutes, fearful that he might miss the plane. By the time the taxi dropped him at the airport, he had reached chapter seven and the death of Stalin’s second wife. He handed another five rubles to the driver and didn’t wait for the change, but ran into the airport and followed the signs for the BOAC counter.

“Can you get me on the nine ten back to London?”

“First or economy?” asked the booking clerk.

“First.”
