Neville St. Clair

Neville St. Mrs. St. Clair is a respectable gentleman whose sudden disappearance throws his wife into turmoil. Living in the suburbs with his family, he maintains the outward appearance of a man of means and propriety. His devoted wife, Mrs. St. Clair, trusts him implicitly, yet finds him seen in a window in Swandam Lane, a location she can scarcely believe he would visit. St. Mrs. St. Clair leaves behind puzzling clues—his signet ring arrives in a letter postmarked from Gravesend, written in his own hand, assuring his wife that all will be rectified though there has been a "huge error." His sudden reappearance and the true circumstances of his disappearance remain subjects of Sherlock Holmes' investigation, touching on questions of identity, disguise, and the secrets respectable men may conceal from those closest to them.
