"I've always believed in writing without a collaborator, because where two people are writing the same book, each believes he gets all the worry and only half the royalties"

Agatha Christie's quote speaks to the idea that composing is a singular undertaking. She believes that when 2 people work together on a book, each person is handling the full concern of the work, however just receiving half of the benefits. This suggests that Christie values the individual effort of composing and the benefits that come with it. She believes that when two people team up, the work is not as gratifying as when one person takes on the entire project. This quote also talks to the idea that composing is an imaginative procedure that needs a good deal of effort and dedication. Christie's quote is a reminder that writing is a personal journey which the rewards should be shared equally.
