Gunther had a suite in one of the newer hotels that tower over the eastern entrance to the park. When Beecher arrived, a quiet, powerfully built man was standing in front of the fireplace, smoking with enjoyment. Beecher recognized immediately Cyrus McKenna, formerly of the United States Secret Service, founder of the great detective agency that bore his name.

"Ted, shake hands with my good friend Mr. McKenna," said Gunther, appearing in the doorway with a refractory collar in his grasp. "McKenna, shake hands with Mr. Beecher. Fire away, Ted. I'll be out in a second."

"Glad to know you," said McKenna, grasping his hand.

Beecher was aware of the quick, estimating scrutiny and a sense of unusual physical vitality. But he was disappointed in his first glance at this man whose investigations had been the terror of corrupt politicians and unscrupulous agitators. McKenna was physically the ideal detective, in that not a feature possessed a trace of oddity which could betray him to the public, in which he thus mingled without fear of recognition. He was neither short nor tall, neither thin nor unusually heavy. His head was round, well-spaced, and evenly formed, without affectation of mystery or astuteness, lit up by a jovial good humor when animated, and quite blank and indecipherable when in repose. The eyes alone, like the eyes of a painter or a sculptor seeking tones or modelings that escape the common glance, were noticeable for a certain quality of penetration, expressed in the countenance by innumerable fine lines that gathered in the eye-pits.

"Mr. McKenna," said Beecher, who had an instinctive desire to impress the detective with the lucidity of his observations, "I will give you quickly the details that are important. First, here is the plan of the apartment, which may or may not be of use."

He went to the low table-desk at the side, and drew out paper and pencil. McKenna brought up a chair at his side, and Gunther, coming in, sat down opposite.

"It concerns the theft of a ruby ring worth over fifteen thousand dollars," said Beecher, busy with his pencil, "taken last night, between eight and eleven, at the apartment of Mrs. Rita Kildair. The circumstances are so extraordinary that you will be interested in the problem itself."

The detective smiled in a slightly amused way and asked:

"Am I retained in her interest or in yours?"

"In mine," said Beecher quickly. "The theft took place at a social gathering, you understand, and in the party were persons well known in New York society. Mrs. Kildair, as is natural, particularly desires that nothing shall become public."
