Comment

Park Lane was renumbered in the years after Watson wrote his account. T. B. Wheeler stated the northern house (129 Park Lane) was the Adair residence and that Ronald Adair was sitting in a second floor room which had a window overlooking Green Street. Moran entered No 128 (the southern house) and shot him from one of its side windows on the south side of Green Street.
