Ayrton spoke quite calmly and firmly. Glenarvan looked at him for an instant, and then sent to summon McNabbs and Paganel, who came at once.

“We are all ready to listen to you,” said Glenarvan, when his two friends had taken their place at the saloon table.

Ayrton collected himself, for an instant, and then said:

“My Lord, it is usual for witnesses to be present at every contract or transaction between two parties. That is why I desire the presence of Messrs. Paganel and McNabbs, for it is, properly speaking, a bargain which I propose to make.”

Glenarvan, accustomed to Ayrton’s ways, exhibited no surprise, though any bargaining between this man and himself seemed strange.

“What is the bargain?” he said.

“This,” replied Ayrton. “You wish to obtain from me certain facts which may be useful to you. I wish to obtain from you certain advantages which would be valuable to me. It is giving for giving, my Lord. Do you agree to this or not?”

“What are the facts?” asked Paganel eagerly.

“No,” said Glenarvan. “What are the advantages?”

Ayrton bowed in token that he understood Glenarvan’s distinction.
