The sudden retreat of Ralph and his party left Nattie and Mori staring after them as if powerless to move. Their inaction did not last long, however. Wild with rage they darted across the drawbridge, but only to find the portcullis—an arrangement of timbers joined across one another after the manner of a harrow—barring their way.

Seizing one part of it, Nattie attempted to force himself through, but he was met with a bullet that whizzed past his head in dangerous proximity to that useful member. Simultaneous with the report there appeared on the other side Ralph and the ex-bookkeeper.

Both carried revolvers, which they flourished menacingly. Deeming discretion the better part of valor, Nattie and Mori dodged behind a projecting corner of the massive entrance. A taunting laugh came to their ears.

"Why don't you come in and rescue your brother, you coward?" called out the merchant's son. "What are you afraid of?"

The epithet and the insulting tone was too much for Nattie's hot young blood, and he was on the point of rushing forth from his shelter, regardless of consequences, when he was forcibly detained by Mori.

"Stop! Don't be foolish," explained the young Japanese. "He is only trying to get a shot at you."

"But I can't stand being called a coward by a cur like that."

"We will repay him in good time. We have them cornered, and all we have to do is to see that they don't get away while we send for the authorities. Don't ruin everything by your rashness."
