o the hands of the woman who is at the
bottom of this and every other case, and she reads the synopsis from
sheer curiosity. The case fits her case, and there you are. Mind you, I
don't say that this is how the thing actually happened, but how it might
have done so. When did you post the letter?"

"I can't give you the date. Say ten days ago."

"And there would be no hurry for a reply," Bell said, thoughtfully. "And
you had no cause for worry on that head. Nor need the woman who found it
have kept the envelope beyond the delay of a single post, which is only a
matter of an hour or so in London. If you go a little farther we find
that money is no object, hence the L1,000 offer and the careful, and
doubtless expensive, inquiry into your position. Steel, I am going to
enjoy this case."

"You're welcome to all the fun you can get out of it," David said,
grimly. "So far as I am concerned, I fail to see the humour. Isn't this
the office you are after?"

Bell nodded and disappeared, presently to return with two exceedingly
rusty keys tied together with a drab piece of tape. He jingled them on
his long, slender forefinger with an air of positive enjoyment.

"Now come along," he said. "I feel like a boy who has marked down
something rare in the way of a bird's nest. We will go back to Brunswick
Square exactly the same way as you approached it on the night of the
great adventure."

CHAPTER IX

THE BROKEN FIGURE

"Any particular object in that course?" David asked.

"There ought to be an object in everything that even an irrational man
says or does," Bell replied. "I have achieved some marvellous results by
following up a single sentence uttered by a patient. Besides, on the
evening in question you were particularly told to approach the house from
the sea front."

"Somebody might have been on the look-out near the Western Road
entrance," Steel suggested.

"Possibly. I have another theory.... Here we are. The figures over the
fanlights run from 187 upwards, gradually getting to 219 as you breast
the slope. At one o'clock in the morning every house would be in
darkness. Did you find that to be so?"

"I didn't notice a light anywhere till I reached 219."

"Good again. And you could only find 219 by the light over the door.
Naturally you were not interested in and would not have noticed any other
number. Well, here is 218, where I propose to enter, and for which
purpose I have the keys. Come along."
