ngerous lunatic," said he. "Just go up and look at his
green." And he continued his way, his countenance brightened by a
pleasant anticipation of a cheerful affray round an easel in the
gloaming, and the shedding of much green paint.

But to Person and Wainwright Mr Watkins was less aggressive, and
explained that the green was intended to be the first coating of his
picture. It was, he admitted in response to a remark, an absolutely
new method, invented by himself. But subsequently he became more
reticent; he explained he was not going to tell every passer-by the
secret of his own particular style, and added some scathing remarks
upon the meanness of people "hanging about" to pick up such tricks of
the masters as they could, which immediately relieved him of their
company.

Twilight deepened, first one then another star appeared. The rooks
amid the tall trees to the left of the house had long since lapsed
into slumbrous silence, the house itself lost all the details of its
architecture and became a dark grey outline, and then the windows of
the salon shone out brilliantly, the conservatory was lighted up, and

takes the candle away and goes down to supper, we'll call in. My! how
nice the house do look, to be sure, against the starlight, and with
all its windows and lights! Swopme, Jim, I almost wish I _was_ a
painter-chap. Have you fixed that there wire across the path from the
laundry?"

He cautiously approached the house until he stood below the
dressing-room window, and began to put together his folding ladder.
He was much too experienced a practitioner to feel any unusual
excitement. Jim was reconnoitring the smoking-room. Suddenly, close
beside Mr Watkins in the bushes, there was a violent crash and a
stifled curse. Someone had tumbled over the wire which his assistant
had just arranged. He heard feet running on the gravel pathway beyon
