quirk

There was the quirk in her brain; we all have a quirk somewhere, and that was hers.

I've thought of every possibility, every possible crook and quirk of this business.

Through his thoughts a quirk of memory ran like a tongue of flame.

Was it the strong connection of contrast, or was it a quirk of my brain?

If Quirk might be compared to an old file, Gammon was the oil!

In fact, Quirk was thoroughly afraid of Gammon, and Gammon knew it.

A month or two later, a valuable addition was made to it in Quirk's scouts.

Quirk′ish, consisting of quirks; Quirk′y, abounding in quirks.
