"Now's your time, sir," roared the semaphoric policeman. Had Tom been in a less exposed position it is possible that he might have acted upon that well-timed remark from the cunning constable. The centre of a London crossing is not, however, a very advantageous spot for the performance of love passages. As they walked on, threading their way among the vehicles, Tom took his companion's hand in his, and they exchanged one firm grip, which each felt to be of the nature of a pledge. How sunny and bright the dull brick-lined streets appeared to those two young people that afternoon. They were both looking into a future which seemed to be one long vista of happiness and love. Of all the gifts of Providence, surely our want of knowledge of the things which are to come upon us is the most merciful, and the one we could least dispense with! So happy and so light-hearted were these two lovers that it was not until they found themselves in Warwick Street once more that they came down from the clouds, and realized that there were some commonplace details which must be dealt with in one way or another. "Of course, I may tell my own people, dearest, about our engagement?" Tom said. "I wonder what your mother will say?" answered Kate, laughing merrily. "She will be awfully astonished." "How about Girdlestone?" asked Tom. The thought of the guardian had never occurred to either of them before. They stared at each other, and Kate's face assumed such an expression of dismay that her companion burst out laughing. "Don't be frightened, darling," he said. "If you like, I'll go in and 'beard the lion in his den.' There is no time like the present." "No, no, dear Tom," she cried eagerly. "You must not do that." It was impossible for her to tell him how especially Girdlestone had cautioned her against him, but she felt that it would never do to allow the two to meet. "We must conceal our engagement from Mr. Girdlestone." "Conceal our engagement!" "Yes, Tom. He has warned me so often against anything of the sort, that really I don't know what he would do if he knew about it. He would certainly make it very uncomfortable for me to live with him. Remember I am nearly twenty now, so in a little more than a year I shall be entirely free. That is not very long." "I don't know about that," Tom said doubtfully. "However, if you will be more comfortable, of course that settles the question. It seems rather hard, though, that we should have to conceal it, simply in order to pacify this old bear." "It's only for a time, Tom; and you may tell them at home by all means. Now, good-bye, dear; they will see you from the windows if you come nearer." "Good-bye, my darling."
