A picture is worth how many words?

I thoroughly enjoy graphic novels.  I do not have too many that come across my desk, however.  But I have this one my Denise Mina, a writer whose crime novels I ] have enjoyed in the past.  She writes Scottish noir and does dark well.  She has also done comics in HellBlazer.  A SICKNESS IN THE FAMILY, by DC Comics, Vertigo Crime, 978-1-4012-1081-6.  Drawn by Antonio Fuso.  Fuso has drawn such comics as Fear Agent and others.  He lives in Italy.  The book  This is the morbid tale of the family Usher.   They  are renovating the home after a tragedy makes the other half of the house available to them.  The family are a wife and husband, a son and daughter, and the wife's  mother.  There is also the wife's lover and some other mentioned friends.  There is a great deal of animosity shown in their acts and their conversations.  But things turn deadly.  Death and illness attack the family.  Is it the evilness of the house?  Do stories of witchcraft in the early history of the house have anything to do with the events?  Who is trying to kill whom?  Secrets and grudge fed hatreds make for a surprising and rather grotesque ending.  The stark art work lends to the atmosphere of gloom and despair of this noir graphic. It has a well developed plot and storyline. Families can be deadly.
