"Now I will tell you what we are bent on," Walter said. "From some words I overheard I believe that some of the ruffians over in the marshes are this evening going to make an attack upon a boat with a lady in it coming down the river. We will be on the spot, and can give them a reception such as they do not expect."

"Do you know who the lady is, Walter?"

"I have not the least idea. I only caught a few words, and may be wrong; still it will do no harm should I be mistaken."

The tide was running down strongly, for there had been a good deal of rain during the preceding week, and all night it had poured heavily. It was fine now, but the stream was running down thick and turbid, and it needed all the boys' efforts to force the wherry against it. They rowed by turns; all were fairly expert at the exercise, for in those days the Thames was at once the great highway and playground of London. To the wharves below the bridge ships brought the rich merchandise of Italy and the Low Countries; while from above, the grain needed for the wants of the great city was floated down in barges from the west.

Passing the Temple, the boys rowed along by the green banks and fields as far as Westminster, which at that time was almost a rival of the city, for here were the abbey and great monastery; here were the king's palace and court, and the houses of many of his nobles. Then they went along by the low shores of Millbank, keeping a sharp lookout for boats going down with the stream. It was already getting dark, for Walter had not allowed for the strength of the stream, and he was full of anxiety lest he should arrive too late.


CHAPTER III.

A THWARTED PLOT.

A boat was rowing rapidly down the stream. It had passed the village of Chelsea, and the men were doing their best to reach their destination at Westminster before nightfall. Two men were rowing; in the stern sat a lady with a girl of about eleven years old. A woman, evidently a servant, sat beside the lady, while behind, steering the boat, was an elderly retainer.

"It is getting dark," the lady said; "I would that my Cousin James had not detained us so long at Richmond, and then after all he was unable to accompany us. I like not being out on the river so late."
