oor. There was
something familiar about his back, and Kennedy and I started after him.
But we were too late. He had fled without even waiting for his hat,
which lay on Miss Golder's desk, and had disappeared down a back
stairway which had been left unguarded.

"Confound it," muttered O'Hanlon, as we returned, "Loeb hasn't been here
today. Who was that?"

"I don't know," replied Craig, picking up the hat, underneath which lay
a package.

He opened the package. Inside were half a dozen Berkefeld filters, those
peculiar porcelain cones such as we had found out at Norwood.

Quickly Craig ran his eye over the mass of papers on Miss Golder's desk.
He picked up an appointment book and turned the pages rapidly. There
were several entries that seemed to interest him. I bent over. Among
other names entered during the past few days I made out both "Moreton"
and "Dr. Goode." I recalled the letter which O'Hanlon had received from
Moreton. Had he or someone else got wind of the raids and tipped off Dr.
Loeb?

Above the hubbub of the raid I could hear O'Hanlon putting poor little
Miss Golder through a third degree.

"Who was it that went out?" he shouted into her face. "You might as well
tell. If you don't it'll go hard with you."

But, like all women who have been taken into these get-rich-quick
swindles, she was loyal to a fault. "I don't know," she sobbed, dabbing
at her eyes with a bit of a lace handkerchief.

Nor could all of O'Hanlon's bulldozing get another admission out of her
except that it was a "stranger." She protested and wept. But she even
rode off in the patrol wagon with the rest of the employes unmoved.

Whom was she shielding? All we had was the secretary, a couple of
cappers, and half a dozen patients, regular and prospective, who had
been waiting in the office. We had a wagon-load of evidence, including
letters and circulars, apparatus of all kinds, medicines, and pills. But
there was nothing more. Craig did not seem especially interested in the
mass of stuff which the police had seized.

In fact the only thing that seemed to interest him was the man who had
disappeared. We had his hat and the package of filters. Craig picked up
the hat and examined it.

"It's a soft hat and consequently doesn't tell us very much about the
shape of his head," he remarked. Then his face brightened. "But he
couldn't have left anything much better," he remarked complacently, as
he went over to one of the little wall cabi
