Receiving directions from Mrs. Barcroft the two chums set off on their quest. Half way down the lane leading to the Dingle Dell they suddenly encountered Philip Entwistle.
"Mornin'," said Billy with a laugh. "How are you? Recovered from that donkey-trip of ours yet?"
"Quite—absolutely," replied Entwistle. "So you are on leave again? I'm glad—very glad. There's a little matter upon which I should like to speak."
He paused and glanced inquiringly at Billy's, companion. The A.P. discreetly began to walk on.
"I say, Kirkwood," called out the flight-sub. "Let me introduce you."
"So you are the man who was flying with our friend here when the German airman who bombed Alderdene was strafed," said Entwistle, after the introduction was made.
"I believe I had a hand in it," admitted Kirkwood.
"That was when the document setting a price on your father's head was discovered, Barcroft," continued the vet.
"I say—how did you know that?" asked Billy. "Funny how things like that leak out."
"It's part of my business," replied Entwistle gravely. "That is the matter on which I wish to speak to you, and since Mr. Kirkwood is 'in the know' up to a certain point I do not see any reason why he should not be admitted into our conference. First of all, let me say that for the present I must get you to promise not to say a word to your father, or in fact to any one concerning what I am about to divulge." The two officers gave the required promise.
