Suddenly his memory clicked into gear and he frowned.

A memory clicked into place then, like a key in a lock.

Clicking a button on the screen clears the camera's memory.

Puzzled, he stared at them for a moment, then full memory clicked back in place.

The memories clicked into place, unbidden, at the sound of the word.

A memory clicked into the framework of her story.

And just as abruptly, a memory, a very old memory, clicked into place.

Then the older one of them smiled, and the memory clicked into place.

He knew the instant that the right memory clicked into place.

The memories are clicking faster now, like terrible flashes from a nightmare.
