"They didn't file neither the chain nor the cuffs," explained Kansas, wearily. "They unlocked the cuffs."
"Unlocked 'em, huh? Where'd they get the key? Lose one of yores, did yuh?"
"Ours is all safe. They must 'a' had a key. Anyway, there's the handcuffs wide open when I found McFluke gone this mornin'."
Dolan pulled out his watch. "Nine o'clock," said he. "When did you first find Mac was gone, Kansas?"
"When I took his breakfast in less'n five minutes ago."
"Howcome you went to the warehouse so late?"
"Well," said Kansas, somewhat shamefacedly, "we didn't lock him up in the warehouse till one o'clock this morning, and I figured a li'l extra sleep wouldn't do him any harm."
"Or a li'l extra sleep wouldn't do yoreself any harm neither, huh?"
"Maybe I did sleep later than usual," admitted Kansas.
"I guess you did," said Dolan. "I guess you did. And Jake, too. Told anybody else about this?"
