That had been an hour ago and as the train pulled out I saw the man opening a paper behind the grimy glass.

He pointed to the chair facing the grimy one-way glass.

In fact, no one had ever seen a person enter through that door with the grimy, cobwebbed glass.

A flash of movement caught his eye and, leaning forward, he rubbed at the grimy glass.

Rubbing her hand across the grimy glass to clear it, she peered inside.

Outside the window, the sky had darkened and a few splashes of rain ran down the grimy glass.

Lights shone from the office, and Bolan detected movement behind the grimy glass of one window.

For a moment the water below him looked like some window, glazed with grimy glass, through which he was peering.

Before he stuck it back in place, blocking out the world, he stared through the grimy glass.

Lloyd rubbed the grimy glass with the side of his hand, but he couldn't distinguish very much more.
