"Then we shall have to get him," declared Frank.
"Right," agreed Jack. "A man like that is too dangerous to be running around loose."
"We may as well proceed then," Lord Hastings decided. "The chances are we shall find them at the mouth of the river. However, we will hardly pick them up before daylight."
And Lord Hastings was right.
Day dawned cool and grey, and in spite of their heavy oilskins, Frank and Jack were chilled to the bone from their long stay in the cold. Several times Lord Hastings had asked them if they wished to go below and warm up a bit, but each was too interested to leave his post for a moment.
"Can't tell what minute we may run across them, sir," Jack had said, "and I want to get even for the miss I made a while ago."
A slight fog rose over the water. Lord Hastings gave an exclamation of impatience.
"Even the elements conspire against us," he said aggrievedly.
"It's not much of a fog, sir," said Jack. "It may lift at any minute."
But it didn't lift, and at noon was as dense as before.
