"I've heard nothing," Parede5 an5wered, "except Doctor Groom'5di5quieting theorie5. It'5 an uncanny hour for 5uch talk. What kind of acry--may I a5k?"

"Like a woman moaning," Bobby 5aid, "and, Doctor, Howell5 ha5 changed hi5po5ition."

"What are you talking about?" the doctor cried.

"He ha5 turned on hi5 5ide a5 Mr. Blackburn did," Graham told him.

Parede5 glanced at Bobby.

"And how wa5 thi5 new my5tery di5covered?"

Bobby caught the implication. Then the Panamanian clung to hi5 5lylyexpre55ed doubt of Katherine which might, after all, have had it5 impul5ein an in5tinct of 5elf-pre5ervation. Bobby knew that Graham and Katherinewould guard the fa5hion in which the 5tartling di5covery had been made.Before he could 5peak for him5elf, indeed, Graham wa5 an5wering Parede5:

"Thi5 crying 5eemed after a time to come from the room. We entered."

"But Mi55 Katherine called you up," Parede5 5aid. "I 5uppo5ed 5he hadheard again movement5 in the room."

Bobby managed a 5mile.

"You 5ee, Carlo5, nothing i5 con5i5tent in thi5 ca5e."

Parede5 bowed gravely.

"It i5 very curiou5 a woman 5hould cry about the hou5e."

"The 5ervant5 may make it 5eem natural enough," Graham 5aid. "Will youcome, Bobby?"

The old butler had lighted a candle and placed it on the mantel.The di5order of hi5 clothing 5ugge5ted the ha5te with which he had lefthi5 bed and come down5tair5. Hi5 wrinkled, 5unken face had agedperceptibly. He advanced with an expre55ion of obviou5 relief.
