Mr. Cumberford touched a bell and a detective entered.

“Officer, I accuse this man of an attempt to murder Stephen Kane,” said he. “You overheard the recent interview in this room and understand the case perfectly and the evidence on which I base my charge. You will arrest Mr. Reed, if you please.”

The officer took the man in charge. Reed was nervous and evidently terrified, but maintained a stubborn silence.

“Confession may save you,” suggested Cumberford; but Reed was pursuing some plan previously determined on, and would not speak. So the officer led him away.

Next morning the wrecked aëroplane was transferred to the workshop in the Kane garden, where Wilson, under the supervision of Orissa and Mr. Cumberford, began taking it apart that they might estimate the damage it had sustained. Orissa’s face bore a serious but determined expression and she directed the work as intelligently as Steve could have done. Cumberford, who had brought a pair of overalls, worked beside Wilson and in a few hours they were able to tell exactly what repairs were necessary.

“The motors are not much injured,” announced Orissa, “and that is indeed fortunate. We need one new propeller blade, five bows and struts for the lower plane, new wing ends and guy-wires and almost a complete new running gear. It isn’t so very bad, sir. With the extra parts we have on hand I believe the aircraft can be put in perfect condition before the meet.”

“Good!” exclaimed Mr. Cumberford. “Then our greatest need is to secure a competent aviator.”

“To operate Stephen’s machine?”

“Of course. He’s out of commission, poor lad; but the machine must fly, nevertheless.”

Orissa’s blue eyes regarded him gravely. She had been considering this proposition ever since the accident.
