Bending low, he moved hurriedly across the roof, dropped down on another roof, followed by Solly.

A shot rang out.

Four roofs away, Tux could see Rose’s skylight.

“Cops!” Solly muttered, and slid like a shadow towards a line of chimneys.

Tux hesitated, then followed him.

As they crouched in the shadows, Tux caught sight of four cops climbing through a nearby skylight. They spread out and began to move cautiously forward.

“They’ll walk right into us!” Tux snarled.

Solly pulled a .38 from inside his coat.

“Yeah,” Tux said. “Get them before they get us. I’ll take the outside guy. You take the one on the left.”

They both fired.
