Re: Claus

Date: December 24

Target Claus was spotted at workshop but gave me the slip.  Picked up trail and located him again in Brooklyn at apartment of Mrs. Ida Sessions.  Have photographs of Claus going down Mrs. Sessions back chimney, which is illegal in New York State.  Photographs under sealed separate cover.

Tailed target to subway, which was taken to High Street stop in Brooklyn Heights.  Was able to photograph target without being noticed as he climbed the stairs.  See below.

Target lost after this encounter.  At this point target put his finger to his nose and up the stairs he rose.  Gone when I got to the street.  Pursuing.
