faces to the wall. Bell began idly to turn
the latter over.

"I am a maniac on the subject of old prints," he explained. "I never see
a pile without a wild longing to examine them. And, by Jove, there are
some good things here. Unless I am greatly mistaken--here, Steel, pull up
the blinds! Good heavens, is it possible?"

"Found a Sistine Madonna or a stray Angelo?" David asked. "Or a ghost?
What _is_ the matter? Is it another phase of the mystery?"

"The Rembrandt," Bell gasped. "Look at it, man!"

Steel bent eagerly over the engraving. An old print, an old piece of
china, an antique jewel, always exercised a charm over the novelist. He
had an unerring eye for that kind of thing.

"Exquisite," he cried. "A Rembrandt, of course, but I don't recollect
the picture."

"The picture was destroyed by accident after Rembrandt had engraved it
with his own hand," Bell proceeded to explain. He was quite coherent now,
but he breathed fast and loud, "I shall proceed to give you the history
of the picture presently, and more especially a history of the
engraving."

"Has it any particular name?" David asked.

"Yes, we found that out. It was called 'The Crimson Blind!'"

"No getting away from the crimson blind," David murmured. "Still, I can
quite imagine that to have been the name of the picture. That shutter
or blind might have had a setting sun behind it, which would account
for the tender warmth of the kitchen foreground and the deep gloom
where the lovers are seated. By Jove, Bell, it is a magnificent piece
of work. I've a special fancy for Rembrandt engravings, but I never saw
one equal to that."

"And you never will," Bell replied, "save in one instance. The picture
itself was painted in Rembrandt's modest lodging in the Keizerskroon
Tavern after the forced sale of his paintings at that hostel in the year
1658. At that time Rembrandt was painfully poor, as his recorded tavern
bills show. The same bills also disclose the fact that 'The Crimson
Blind' was painted for a private customer with a condition that the
subject should be engraved as well. After one impression had been taken
off the plate the picture was destroyed by a careless servant. In a
sudden fit of rage Rembrandt destroyed the plate, having, they say, only
taken one impression from it."

"Then there is only one of these engravings in the world? What a find!"

"There is one other, as I know to my cost," Bell said, significantly.
"Until a few days ago I
