"You will be mystified to receive this from an utter stranger, but I deem it my duty, kind sir, to send this word to you.
"Know, then, that one Ken Gow, a servant of my family, was in Port Arthur up to sixteen days ago—first a servant in an American family there, and next a prisoner in the vilest prison man ever saw, guarded by dogs of Russians unworthy to be used as door mats. Ken Gow is a faithful man, the flower of all my help.
"It is needless to explain to you why my servant was thus ill-treated. But you must know that when in prison he met your great friend Captain Benjamin Russell, and it was the captain who saved Ken Gow from many hard blows from the other prisoners, who wanted not a Chinaman amongst them.
"Ken Gow was grateful, even as I am grateful, and he promised to get word to you of this matter if the Russians granted him his liberty. Finding no fault in my servant he was, after a time, liberated, and watching his chance, left Port Arthur and came home.
"Kind sir, he is grateful to Captain Russell and would do much for him if he could. Yet his most is to send this letter to you, telling you that Captain Russell is alive and held in a Port Arthur prison as a spy. One Russian hates him—his name, Captain Barusky,—and it would appear that this Russian is also your enemy, so beware of him.
"I can tell no more. Ken Gow is sick from his treatment at the hands of the Russian dogs. Accept this miserable assurance of my eternal friendship, and esteem for one I know must be high and illustrious."
"Cheng Mo."
Gilbert read the letter several times and showed it to Major Okopa. It was written in true Chinese style, with a big Chinese seal attached, and was, beyond all doubt, genuine.
"I can't understand one thing," said the young captain. "How did Ben get to Port Arthur?"
"It may be that this Captain Barusky had him taken there, Captain Pennington."
