How does Jekyll’s letter to Lanyon in the excerpt from The Strange Case of Dr. Jekyll and Mr. Hyde create suspense in the story?

Jekyll makes an urgent, alarming request but does not explain why he needs Lanyon’s help or what is at stake. That missing explanation leaves Lanyon—and the reader—wondering what has happened and why the request is so important, creating suspense. The letter is not a warning about an illness or a threat against Lanyon.
