After a little way, he found a crack, and looked in.

"We were all over it the other day and couldn't even find a crack."

He found a small crack between the bottom and the sides.

He found a crack on the other edge, that would enable him to lift the level door when the time came.

Once they've found a crack of pity, believe me, they'll stick their fingers into it any way they can.

I thought I had found a crack in the ice.
