Empty House: The Adventure at the Empty House is a Noble Phantasm of Sherlock Holmes. It allows him to disguise himself as other individuals, including Heroic Spirits. It is not a perfect imitation, since the parameters he imitates cannot exceed his own parameter values, and he cannot use the skills and Noble Phantasms associated with Heroic Spirits he imitates.[1][2][3]

During the events of the Shinjuku Singularity, Holmes used Empty House to disguise himself as Edmond Dantès. He was recognised as a fake when he referred to himself as Edmond Dantès, instead of The Count of Monte Cristo.[2]
