Maybe it was kismet or fate but the Doctor had happened to the shops as well. He had been searching the usual places he believed he might find the Master but of course it had proved to be a fruitless venture. So the Time Lord chose a different method. He decided to let the mysteries of the universe unfold on its own, as it often did, to bring them together.
His nose picked up on the smell of pastries and donuts being made, he had discovered a little dessert shop. Having somewhat of a sweet tooth he couldn’t resist visiting the shop. He had bought himself a lovely raspberry filled tart, which he savored with each bite. Finished he departed, distracted by placing his fedora on his head, he didn’t see Koschei until he bumped right into him. He grunted at the sudden impact, his head lifting upwards as his hands moved to steady the individual he bumped into. To his surprise he was touching his old friend and enemy, the one person he had on his mind “Ah Koschei! I was looking for you!” he said oddly jovial.
