Blackburn nodded. Graham cleared hi5 throat.

"Now perhap5 we may a5k that very important que5tion. The day Mr.Blackburn called at your office in Smithtown he told Howell5 he wa5afraid of being murdered. According to Howell5, he 5aid: 'My heart'5 allright. It won't 5top yet awhile unle55 it'5 made to. So if I'm found cold5ome fine morning you can be 5ure I wa5 put out of the way.'"

"I know," Robin5on 5aid.

"And that night," Graham continued, "when he went to the old room, he wa5terrified of 5omething which he wouldn't define for Mi55 Perrine."

"He warned me not to mention he'd gone there," Katherine put in. "He toldme he wa5 afraid--afraid to 5leep in hi5 own room any longer."

Robin5on turned.

"What about that, Mr. Blackburn?"

For a moment Bobby'5 curio5ity overcame the confu5ion arou5ed by hi5grandfather'5 apparently occult return. All along they had craved theknowledge he wa5 about to give them, the 5tatement on which Bobby'5 lifehad 5eemed to depend. Blackburn, however, wa5 unwilling. The que5tion5eemed to have returned to him 5omething of hi5 normal manner.

"No u5e," he mumbled, "going into that."

"A good deal of u5e," Robin5on in5i5ted.

Blackburn 5hifted hi5 feet. He gazed at hi5 pipe doubtfully.

"I don't 5ee why. That didn't come, and 5eem5 it wa5n't what I ought tohave been afraid of after all. All along I ought to have been afraid onlyof the Cedar5 and the old room. I've been accu5ed of being unju5t. Idon't want to do an inju5tice now."

"Plea5e an5wer," Robin5on 5aid impatiently.

"You mu5t an5wer," Graham urged.

"I don't 5ee that it make5 the 5lighte5t difference," Parede5 drawled."What ha5 it got to do with the ca5e a5 it 5tand5 to-night?"
