Tracey's first instinct once they were outside was to run. But her trembling body couldn't take it, she couldn't leave Timmy, and the state Rick was in he'd couldn't get far.
So she released her grip on him - her teeth bared in pain as her hands freed themselves from their steel grasp - and lowered Timmy to the ground.
Something made her look around at the apartment block. Its uninspiring facade stared mockingly back at her and she turned back to her husband and son.
They weren't there.
Sweet Jesus, no!
Her legs gave way and she wept as she fell.
