Sammy sat on the wall overlooking the Regent's Canal, throwing tiny stones into the water, listening to the plopping sound with half an ear as he kept an eye on Kallie, rattling her tin cup in the direction of the tourists flocking to Camden Market.

"Spare change? Any spare change?"

He smiled, picking out the foreign tourist from the Brits by their generosity.

Kallie scanned the crowds, seeing they were all busy flocking to the shops and stalls. No one had noticed the young boy sitting on the wall. She gave a brief nod and suddenly he was gone, ducking and weaving behind the shops to the row of condemned houses that ran along the canal side.

As soon as he was gone, and she was sure his movements had attracted no unwanted attention Kallie picked up her scruffy backpack before wandering off towards the street, and the front of the derelict row.

Setting herself up at a vantage point on the corner, she continued plead for money while watching the house fronts. She watched as Sammy moved stealthily between the buildings, entering at the front if the back was inaccessible, and she smiled at his housebreaking skills.

But her smile slipped as, moments later, a car pulled up and a familiar figure climbed out and followed Sammy into the building.
