Bishop that Frank was well acquainted with his treachery--that he
dared not deny the charge, and he answered:

"Because, when any of our boys escape, the guards are awful hard on
those of us that are left."

"That's no excuse at all," answered Frank. "If you were a man, you
would have endeavored to escape long ago, instead of staying here
and trying to make friends with the enemies of your country. You're
a black-hearted scoundrel and traitor! and I tell you, once for all,
that if you ever come into my quarters again after dark, you'll never
go out alive. We all know about your operations here."

Bishop made no reply, but turned to walk on, when Frank rose to his
feet, and exclaimed:

"Hold on, here! you are not going through this room with that candle.
Go back instantly where you belong, and don't show your face in here
again."

Bishop saw that Frank was in earnest, and, without saying a word, he
turned and walked into his quarters.

Frank had a twofold object in talking to him as he did. He wanted to
let him know that his fellow-prisoners all knew what he had done, and
he wished, also, to deter him from coming into that room again, as he
had determined to make another attempt at escape that very night. The
traitor had no sooner disappeared than Frank descended the stairs that
led down into the hall, at the foot of which there were two guards
posted.
