ished. To play him a trick, Joseph, when he heard his knock,
put the copy, which was varnished with a special glaze of his own, in
place of the original, and put the original on his easel. Pierre
Grassou was completely taken in; and then amazed and delighted at
Joseph's success.

"Do you think it will deceive old Magus?" he said to Joseph.

"We shall see," answered the latter.

The dealer did not come as he had promised. It was getting late;
Agathe dined that day with Madame Desroches, who had lately lost her
husband, and Joseph proposed to Pierre Grassou to dine at his table
d'hote. As he went out he left the key of his studio with the
concierge.

An hour later Philippe appeared and said to the concierge,--

"I am to sit this evening; Joseph will be in soon, and I will wait for
him in the studio."

The woman gave him the key; Philippe went upstairs, took the copy,

asking him not to call till the following day.

That evening when Joseph returned, bringing his mother from Madame

Agathe, who had followed Joseph, did not understand what he was
saying; but when her son explained what had happened, she stood still,
with the tears in her eyes.

"Have I but one son?" she said in a broken voice.

"We have never yet degraded him to the eyes of strangers," said
Joseph; "but we must now warn the concierge. In future we shall have
to keep the keys ourselves. I'll finish his blackguard face from
memory; there's not much to do to it."

"Leave it as it is; it will pain me too much ever to look at it,"
answered the mother, heart-stricken and stupefied at such wickedness.

Philippe had been told how the money for this copy was to be expended;
moreover he knew the abyss into which he would plunge his brother
through the loss of the Rubens; but nothing restrained hi
