"I thank you, my lord," said Hymbercourt. He then turned to Calli, and asked, "When were these men arrested?"
"More than a fortnight ago," answered Calli.
"How came you to discover they were spies?" asked Hymbercourt.
"I watched them, and their actions were suspicious," replied the Italian.
"In what respect were they suspicious?"
"They went abroad only at night, and one of them was seen near the castle several evenings after dark," responded Calli.
"Is that your only evidence against them?" demanded Hymbercourt.
"It is surely enough," replied Calli, "but if more is wanted, they were overheard to avow their guilt."
"What were they heard to say and where did they say it?" asked Hymbercourt.
"I lay concealed, with six men-at-arms, near the river in the garden of The Mitre Inn, where the spies had been bathing. We heard them speak many words of treason against our gracious Lord Duke, but I did not move in their arrest until the younger man said to his companion: 'I will to-morrow gain entrance to the castle as a pedler and will stab this Duke Charles to death. You remain near the Postern with the horses, and I will try to escape to you. If the gate should be closed, ride away without me and carry the news to the cantons. I would gladly give my life to save the fatherland.'"
