"A request to go to the Hofburg tonight—before Herr Renwick came," she whispered, now thoroughly aroused. "I did not go. The signature was unfamiliar to me."
Herr Windt took a pace toward the window and peered forth through the slats of the blind.
"The Countess Strahni would not have reached the Hofburg," he said quietly. "She would have gone—er—elsewhere!"
"The man in the green limousine!" came suddenly in cryptic tones from the silent Renwick.
"Exactly. He followed the Countess Strahni's fiacre in motor car to the Nordwest Bahnhof."
"And you?"
"We forestalled him—that's all," he said, showing his gold tooth in a most ingratiating smile, but there was a flash in the deep set eyes which explained much to Renwick.
"There was a commotion near the booking-stall," said Renwick.
"Ah, you witnessed?"
"From a distance. I had other affairs."
