"No, I wouldn't," said Mr. Keen. "I tell you frankly that I expect to find her."

"To-day?"

"We'll see," said Mr. Keen guardedly. "Come, Captain, don't look that way! Courage, sir! We are about to execute a turning movement; but you look like a Russian general on his way to the south front."

Harren managed to laugh; they went out, side by side, descended the elevator, and found a cab at the porte-cochère. Mr. Keen gave the directions and followed the Captain into the cab.

"Now," he said, as they wheeled south, "we are first going to visit the Museum of Inscriptions and have this cipher translation verified. Here is the cipher as I copied it. Hold it tightly, Captain; we've only a few blocks to drive."

Indeed they were already nearly there. The hansom drew up in front of a plain granite building wedged in between some rather elaborate private dwelling-houses. Over the door were letters of dull bronze:

AMERICAN MUSEUM OF INSCRIPTIONS

and the two men descended and entered a wide marble hall lined with glass-covered cabinets containing plaster casts of various ancient inscriptions and a few bronze and marble originals. Several female frumps were nosing the exhibits.

An attendant in livery stood in the middle distance. The Tracer walked over to him. "I have an appointment to consult Miss Inwood," he whispered.

"This way, sir," nodded the attendant, and the Tracer signaled the Captain to follow.
