Who is Henry Clerval?

Frankenstein's friend. The Monster's victim. A sword-wielding hunk with a goatee?

Perhaps. But if you are doing an essay on Henry Clerval or preparing for an exam, I would strongly recommend checking out a few alternative sources of information, such as:

• The Characterisation of Henry Clerval on Crossref-it.info
• http://www.english.upenn.edu/Projects/knarf/Chars/clerval.html
• Reading Mary Shelley's Frankenstein
