Adventure Comics #93

Mr. Kendall goes to the Sleepatorium, a special dormitory that puts people to sleep when nothing else works. What he doesn't know, and that the Sandman discovers, is that a fellow patient, a criminal known as Wide-Awake Willie, also uses the facility as a blind to get sleep, when, in reality, he takes a delayed action drug that awakens him at a certain time so that he and his gang can rob Kendall's home.
