They drove south through the city for about fifteen minutes without going back onto the A57 autobahn that had brought her to Chorweiler. Viktor made two stops to collect, both in run-down areas. After the second stop Maria became concerned when she found herself immediately behind Viktor, the two previously intervening cars having turned off at different junctions. She held back as much as she could, but whenever they stopped at traffic lights she ended up bumper to bumper with Viktor. If he looked in his rear-view mirror, he would see her face clearly. She tugged her woollen hat further down over her brow. Maria no longer had a clue where she was, but she tried to make a mental note of the road endings she passed. They were still within the city but the architecture changed from residential to industrial and she became painfully aware that there were fewer cars on the road, making her tailing more conspicuous. Eventually they passed under the autobahn and came into another residential area indicated by a yellow Stadtteil sign as Ossendorf. She noted the name of the road they passed along, Kanalstrasse, and followed Viktor as he turned along a street lined with four-storey apartment blocks. Now her and Viktor’s were the only cars driving along it. Maria decided to break off rather than risk Viktor identifying her as a tail. She took the next on the left, did a U-turn to face the road she had left and parked at the kerb.

Maria cursed under her breath. She took the Cologne street plan from the glove compartment and checked Ossendorf. Her instincts had been right. This was a residential area and not a short cut to anywhere else. Either Viktor lived here or he was doing another pick-up. She would wait half an hour. If it was another pick-up, then he would probably come out of the area before the half-hour was up, and more than likely by the same way he had come in. And if she were unsuccessful either way, then she would watch Slavko’s apartment every day and pick up his trail again.
