He was swiftly dashing through backyards, thanking his guardian angel for the fact that the owners of the houses that the yards belonged to were away at the time. There was a close call with the Yeagers' dog three houses down. He'd have to hurry if he was to make the appointment on time. If he was even a second late his cover would most likely be blown in a rather spectacular manner. His house had been bugged long ago. If he removed the bugs, his cover would be blown. So he'd left them there. One wrong word from his visitor however...
He'd finally reached his own backyard. The fates were smiling upon him, he had twenty minutes to spare. He swiftly entered his home through the window the caretaker had left open for this very reason (In fact, it was the very window the caretaker had left by. They had crossed paths five houses down). He looked around his home, fortunately the caretaker hadn't left too much of a mess. Two instructions manuals lay on his desk complete, waiting only to be proofread and corrected.
He removed all traces of the caretaker from his home, and ran upstairs to his room where he swiftly changed his clothes. With two minutes to spare, he headed down to the entryway and stood by the front door getting into the character of the person he had been long ago.
He greeted his brother, who had, as always, come right on time. One slip up on his part, and the very observant man would blow his cover. Finally, his brother left, unable to stand the house and its occupant a moment longer.
He breathed a sigh of relief, he was safe for now. He would have two whole weeks to himself before he had to get back to his job with the CIA.
Adrian Monk smiled as he got into the passenger side of Natalie's car. He took some amusement from the fact that his brother still didn't realize that he knew, and that he had known for the past twenty years. Ever since one of the plates went missing, and was replaced with an imperfect copy. He kept up the charade because he knew that a slip up on his part would blow his brother's cover. He'd lost Trudy, he wasn't going to lose Ambrose.
