eleven o'clock
I never knew where it would lead me -- I never thought , never cared -- but I looked into the gateway of heaven last night , and I ca n't go down the path to hell any longer . Here is an even half of Miss Wyvern 's jewels . If you and her father would have me hand over the other half to you , and would have ` The Vanishing Cracksman ' disappear forever , and a useless life converted into a useful one , you have only to say so to make it an accomplished thing . All I ask in return is your word of honour -LRB- to be given to me by signal -RRB- that you will send for Sir Horace Wyvern to be at your office at eleven o'clock to-night , and that you and he will grant me a private interview unknown to any other living being . A red and green lantern hung over the doorway leading to your office will be the signal that you agree , and a violet light in your window will be the pledge of Sir Horace Wyvern . When these two signals , these two pledges , are given , I shall come in and hand over the remainder of the jewels , and you will have looked for the first time in your life upon the real face of ` The Man Who Calls Himself Hamilton Cleek .
