ANNIE—THE GUN
But apparently Fritz had overshot the aerodrome, for the next explosion came a mile to the west.
"Tam will see the burst," said young Austin and Blackie nodded.
There were no other explosions and they waited for ten minutes, then—
"Ticka-ticka-ticka-ticka!"
The sound came from right overhead.
"Tam's got him," whooped Blackie; "the devil must have been flying low."
"Tocka-tocka-tocka-tocka!"
"That's Fritz," said Blackie, "and that's Tam again."
Then one of the waving searchlights strayed in their direction, and down its white beam for the space of a hundred yards slid a ghostly white moth. It dipped suddenly and fell out of the light and in its wake, but above, burst three little green balls of fire—Tam's totem and sign-manual.
"Landing lights!" roared Blackie, and they had hardly been switched on when Tam swooped to the ground.
