Douglas pulled out a bit of paper and a pencil that he always had in one or two pockets of his jackets.  As he waited for the doctor and/or the maid to return, he sketched a picture of the maid's face.  He had liked it back in the library when he met her the first time, and now seeing her a second time, he just without planning it, her face began to become created on the paper as he doodled a bit.  He should be sketching the doctor's study, but sometimes the mind took him in its own ways.
