the clock."

Sahwah picked up the receiver. There was a strange buzzing noise on the
wire. "Zig-a-zig, ziz-zig-zig-a-zig, zig-g-g, zig-g-g, zig-g-g-g."
Puzzled at first, she soon recognized what it was. It was the sound of
Joe Lanning's wireless. Joe lived directly back of Sahwah on the next
street, and the aerial of his wireless apparatus was fastened to the
telephone pole in the Brewsters' yard. Joe was "sending," and the
vibrations were being picked up by the telephone wires and carried to
her ear when she had the receiver down. Sahwah understood the wireless
code the boys used, and, in fact, had both sent and received messages.
She knew it was Joe's custom to listen for the time every night as it
was flashed out from the station at Arlington, and then send it to his
friend Abraham Goldstein, a young Jewish lad in the class, who also had
a wireless. Then the two would send each other messages and verify them
the next day. "Oh, what fun," thought Sahwah; "I can get Arlington time
to-night." She asked the operator to look up a new number for her to
keep her off the line and then got out paper and pencil to take down the
message as it went out. As she deciphered it she gasped in astonishment.
She had expected a message something on this order: "Hello, Abraham--how
are you?--Arlington says ten bells--How's the weather in your neck of
the woods?" Instead the words were entirely different. She could not
believe her eyes as she made them out. "Albright going through railway
tunnel--hold him up--get notebook away--keep Brewster out of game." Her
senses reeled as she understood the meaning of the message. That Joe was
plotting against her when he pretended to be a friend cut her to the
quick. For a moment her lip quivered; then her nature asserted itself.
There was a thing to do and she must do it. Dick must be kept from going
through the tunnel. Turning out the lights downstairs, she crept
noiselessly out of the house, found her brother's bicycle on the porch
