At first Isabelle Reichenbach had politely declined the invitation to Diana Sommer's 30th birthday party.

She was new in Halle and, despite deceptive appearances, a shy person at heart.

She met him there. Tim. Who reminded her in many ways of her little brother.

Which was maybe what made it so easy. The dancing, the talking, the laughing.

He was totally useless, to her and possibly to the rest of the world.

And yes, she would call the number he had casually slipped into her coat pocket when they said goodbye.
