"By Jove, this is a serious thing, Mark."

"It is a serious thing. I don't want you to get into a row with the fellow. I should like you to give me a nod when you have satisfied yourself that I was not mistaken. I will take upon myself to denounce the fellow, and to say what I noticed yesterday and you can back me up by saying that you saw the same thing. I have no doubt that I shall be able to convince every decent man there that my charge is well founded. I am going to watch Emerson. With the help he gets from Flash, he won't risk anything by cheating until it comes to a big stake like the last game yesterday, in which case, if Cotter's hand happens to be a strong one, he is likely to do so, and I fancy if he does I shall be able to catch him at it. You had better keep Boldero near you. You can whisper to him what you are watching Flash for, and get him to do so too; as, if I catch Emerson cheating, there is likely to be a row; he can lend a hand if necessary, and, at any rate, his joining in with you will suffice to show his friends that the thing is genuine."
