without
permission."

"That's all as good as done," Strawn assured him. "Now--about them
inquiries you asked me to make yesterday of the secretary of the
American Legion." He drew a scrap of paper from his breast pocket. "I
find that John Drake, Peter Dunlap and Clive Hammond were all in
service, in the ----th Division, which was held up late in January,
1918, for nearly two weeks, in Hoboken, before the War Department could
get transports to send 'em to France. Miles, who enlisted the day war
was declared, was wounded and shipped home late in 1917. He was
discharged as unfit for further service--spinal operation--from a New
Jersey base hospital on January 12, 1918. Furthermore, Judge Marshall
was in New York the whole winter of 1917-'18, attached to the Red Cross
in some legal capacity. He donated his services and--"

"All that doesn't matter now, Captain, but thanks just the same," Dundee
interrupted. "Now if you will both excuse me, I've got a lot of work to

Dundee had not exaggerated. That Monday was one of the busiest days he
had ever spent in all the twenty-seven years of his life. He began,
rather strangely, by visiting half a dozen of Hamilton's hardware

Two other calls--both in office buildings--took up only an hour of his
time, and a taxicab delivered him at Police Headquarters just as the
factory whistles were sirening the news that it was twelve o'clock.

He was lucky enough to find the fingerprint expert, Carraway, in his
cubbyhole of an office, his desk almost crowded out by immense filing
cabinets.

Five minutes later Dundee sat at that desk, photographs of Dexter
Sprague's dead body, just as it had been discovered on the floor of the
trophy room in the Miles home, and a labelled set of fingerprints spread
out before him.

"You're sure there can have been no mistake?" he asked. "No chance that
these fingerprint photographs were _reversed_ when the prints were
made?"

"Not a chance--with my system!" Carraway retorted positively.

"Fine!" Dundee cried. "May I take these photographs?... You have copies,
I presume?"

It was half past two o'clock when Dundee, after a much
