night about nine o'clock
Try it . Remember , at seven-thirty . We 'll be a little late at dinner , but never mind ; it will be early enough for the club . '' Left to my own devices I determined to do a little detective work on my own account , and not only did I succeed in finding an acquaintance who agreed to introduce us at the Vesper Club that night about nine o'clock , but I also learned that Percival DeLong was certain to be there that night , too . I was necessarily vague about Kennedy , for fear my friend might have heard of some of his exploits , but fortunately he did not prove inquisitive . I hurried back to our apartment and was in the process of transforming myself into a full-fledged boulevardier , when Kennedy arrived in an extremely cheerful frame of mind . So far , his preparations had progressed very favourably , I guessed , and I was quite elated when he complimented me on what I had accomplished in the meantime .
