gives Dunn the powers of mind-reading, mind-control, and clairvoyance. He uses these powers maliciously for profit and amusement, but then the drug wears off, leaving him a powerless vagrant again. Shuster provided illustrations, depicting Dunn as a bald man. Siegel and Shuster shifted to making comic strips, with a focus on adventure and comedy. They wanted to become syndicated newspaper strip authors, so they showed their ideas to various newspaper editors. However, the newspaper editors told them that their ideas were insufficiently sensational. If they wanted to make a successful comic strip, it had to be something more sensational than anything else on the market. This prompted Siegel to revisit Superman as a comic strip character. Siegel modified Superman's powers to make him even more sensational: Like Bill Dunn, the second prototype of Superman is given powers against his will by an unscrupulous scientist, but instead of psychic abilities, he acquires superhuman strength and bullet-proof skin. Additionally, this new Superman was a crime-fighting hero instead of a villain, because Siegel noted that comic strips with heroic protagonists tended to be more successful. In later years, Siegel once recalled that this Superman wore a "bat-like" cape in some panels, but typically he and Shuster agreed there was no costume yet, and there is none apparent in the surviving artwork. Siegel and Shuster showed this second concept of Superman to Consolidated Book Publishers, based in Chicago. In May 1933, Consolidated had published a proto-comic book titled Detective Dan: Secret Operative 48. It contained all-original stories as opposed to reprints of newspaper strips, which was a novelty at the time. Siegel and Shuster put together a comic book in a similar format called The Superman. A delegation from Consolidated visited Cleveland that summer on a business trip and Siegel and Shuster took the opportunity to present their work in person. Although Consolidated expressed interest, they later pulled out of the comics business without ever offering a book deal because the sales of Detective Dan were disappointing. Siegel believed publishers kept rejecting them because he and Shuster were young and unknown, so he looked for an established artist to replace Shuster. When Siegel told Shuster what he was doing, Shuster reacted by burning their rejected Superman comic, sparing only the cover. They continued collaborating on other projects, but for the time being Shuster was through with Superman. Siegel wrote to numerous artists. The first
