d had shot at her.

Mr. McDonald said afterward he knew her all the time, and was uncertain
whether she was taking a cure for something or was trying to commit
suicide. He said he spent a wretched morning. At five o'clock that
evening we began to hear a curious tapping noise from the spy's island.
It would last for a time, stop, and go on.

Hutchins said it was woodpeckers; but Tish looked at me significantly.

"Wireless!" she said. "What did I tell you?"

That decided her next move, for that evening she put some tea and canned
corn and a rubber blanket into the canoe; and in fear and trembling I
went with her.

"It's going to rain, Lizzie," she said, "and after all, that detective
may be surly; but he's doing his duty by his country. It's just as
heroic to follow a spy up here, and starve to death watching him, as it
is to storm a trench--and less showy. And I've something to tell him."

The canoe tilted just then, and only by heroic effort, were we able to
calm it.

"Then why not go comfortably in the motor boat?"

Tish stopped, her paddle in the air. "Because I can't make that dratted
engine go," she said, "and because I believe Hutchins would drown us all
before she'd take any help to him. It's my belief that she's known him
somewhere. I've seen her sit on a rock and look across at him with
murder in her eyes."

A little wind had come up, and the wretched canoe was leaking, the
chewing gum having come out. Tish was paddling; so I was compelled to
sit over the aperture, thus preventing water from coming in. Despite my
best efforts, however, about three inches seeped in and washed about me.
It was quite uncomfortable.

The red-haired man was asleep when we landed. He had hung the comfort
over a branch, like a tent, and built a fire at the end of it. He had
his overcoat on, buttoned to the chin, and his head was on his
suit-case. He sat up and looked at us, blinking.

"We've brought you some tea and some canned corn," Tish said; "and a
rubber blanket. It's going to rain."

He slid out of the tent, feet first, and got up; but when he tried to
speak he sneezed. He had a terrible cold.

"I might as well say at once," Tish went on, "that we know why you are
here--"

"The deuce you do!" he said hoarsely.

"We do not particularly care about you, especially since the way you
acted to a friendly and innocent cat--one can always judge a man by the
way he treats dumb animals; but we sympathize with your errand
