'Oh, I almost forgot—here's a letter for you.'

'Where—'

'It came in the Maxineffs' mail this morning. Mrs. Max suggested my bringing it to you.'

Noakes took the long, foreign-stamped envelope. The typed superscription was noncommittal, but at the Berlin postmark his eyes narrowed and the knuckles of the hand by his side whitened. He drew a quick breath and looked keenly at the girl.

'Was Mr. Maxineff at home this morning?' he asked quietly.

'No; I believe he is in the city.'

'Oh!' he breathed. 'Thank you very much.'

He slipped the letter into his pocket.

'Well, I can't stay any longer.'

Noakes pressed her hand.
