That evening, in his apartment, Mr. Utterson has further reason to be interested in Mr. Hyde because Dr. Jekyll's will has an unusual clause that stipulates that Edward Hyde is to be the sole beneficiary of all of Jekyll's wealth and property. Utterson goes, therefore, to visit an old friend, Dr. Lanyon, who tells him that some ten years ago, he and Dr. Jekyll became estranged because of a professional matter. Utterson decides to seek out Hyde, and he posts himself as a sentinel outside the mysterious door previously mentioned by Enfield. After some time, Utterson encounters the man Hyde entering the door, and he initiates a conversation with him. Hyde suddenly becomes highly suspicious of Utterson's interest in him and quickly retreats inside the door. Utterson walks around the block and knocks at the front door of Dr. Jekyll's house. Upon questioning the butler, Poole, Utterson discovers that Edward Hyde has complete access to Jekyll's house.
