half past seven
You can understand how essential it is that everything goes just as I planned it . If there 's a slip-up anywhere it means my life . ` Red Mike ' has told me that he 'll kill me if he finds that he has been double-crossed . `` That 's all I need to tell you , I think , except that you will meet my detectives outside this building at half past seven . I 'm doing this to save the lives of the passengers on the ` Lark ' and to show the people of Los Angeles that the detectives of the police department , as I have charged , are n't on their jobs . It should convince them that there is something at least in what I have been saying . '' He glanced at his watch again .
