Dillon scowled darkly, but did not interrupt.

“We will return them to you for a price,” Margate continued. “What that sum shall be, and when the deal can be completed, are the only two questions to be settled.”

“Ah, indeed?” queried Esterveldt, frowning. “What about this detective and his assistant, the one you say is in your hands?”

“You may dispose of them as you please, Baron Esterveldt,” Margate said coldly. “I can imagine that your subsequent safety will permit of only one course.”

“There is some truth in that.”

“We can take care of him,” snapped Irma Valaska, with a fiery glance at the unruffled detective. “We’ll be sure to close his mouth.”

“Possibly.”

Nick dropped in the single doubtful word indifferently.
