“You’re a cheerful fellow, Battle. When will you get me, I wonder?”

“Plenty of rope, sir,” quoted the superintendent, “plenty of rope.”

“In the meantime,” said Anthony, “I am still the amateur assistant?”

“That’s it, Mr. Cade.”

“Watson to your Sherlock, in fact?”

“Detective stories are mostly bunkum,” said Battle unemotionally. “But they amuse people,” he added, as an afterthought. “And they’re useful sometimes.”

“In what way?” asked Anthony curiously.

“They encourage the universal idea that the police are stupid. When we get an amateur crime, such as a murder, that’s very useful indeed.”

Anthony looked at him for some minutes in silence. Battle sat quite still, blinking now and then, with no expression whatsoever on his square placid face. Presently he rose.

“Not much good going to bed now,” he observed. “As soon as he’s up, I want to have a few words with his lordship. Anyone who wants to leave the house can do so now. At the same time I should be much obliged to his lordship if he’ll extend an informal invitation to his guests to stay on. You’ll accept it, sir, if you please, and Mrs. Revel also.”
