"Thanks, chief! And thanks, Captain!" Dundee cried, with heartfelt gratitude. "First, I want to be excused from attending the adjourned inquests into the two murders, scheduled for three o'clock today."

"O.K." Sanderson agreed shortly.

"Second, after about an hour of routine stuff, I wish you'd ask for another adjournment until tomorrow, on the plea that important developments are expected today."

"O.K. again!"

"Third, I'd like you personally to request the appearance of every person connected in any way with each of the murders, in your office this afternoon at four o'clock—so the whole bunch will be kept together and have no chance to go to their homes or anywhere else until I am ready for them. You can say that, owing to the illness of your mother during the investigations, you want to question everyone personally."

"Do you want all the servants brought here, too?" Sanderson asked.

"None but Lydia Carr," Dundee answered. "After about an hour's innocuous questioning, please invite them to accompany you to the Selim house. For that—" and he grinned, "—is where the pot is scheduled to boil over. I'd like everybody to be there by 5:15."

"Where do I come in?" Captain Strawn demanded, almost jealously.

"Now that you are no longer looking for a New York gunman, I suppose you have plenty of plainclothesmen at your disposal?" Dundee asked, and was instantly sorry he had reminded his former chief of the collapse of his cherished and satisfying theory.

"Plenty," Strawn answered gruffly. "How many will you need?"
