tapo chief, in order
to identify him, checks the passport's top number with the picture and
the handwriting received by diplomatic pouch.

Rudolf Walter Voigt, _alias_ Walter Clas, _alias_ Heinz Leonhard,
_alias_ Herbert Frank--names which he used throughout Europe in his
espionage work will serve as an illustration. Voigt was sent to Prague
on a delicate mission. His job was to discover how Czechs got to Spain
to fight in the International Brigade, a mystery in Berlin since such
Czechs had to cross Italy, Germany or other fascist countries which
cooperate with the Gestapo.

Voigt was given passport No. 1,128,236 made out in the name of Walter
Clas, and bearing at the top of the passport the letters and numbers
1A1444. He was instructed, by Leader Wilhelm May of Dresden, to report
to the Henlein Party headquarters upon his arrival in Prague. Clas,
_alias_ Voigt, arrived October 23, 1937, reported at the Sudeten Party
headquarters and saw a man whom I was unable to identify. He was
instructed to report again four days later, since information about
the agent had not yet arrived.

Voigt was trained in the Gestapo espionage schools in Potsdam and
Calmuth-Remagen. He operates directly under Wilhelm May whose
headquarters are in Dresden. May is in charge of Gestapo work over
Sector No. 2. Preceding the granting to Hitler of the Sudeten areas in
Czechoslovakia, the entire Czech border espionage and terrorist
activity was divided into sectors. At this writing the same sector
divisions still exist, operating now across the new frontiers. Sector
No. 1 embraces Silesia with headquarters at Breslau; No. 2, Saxony,
with headquarters at Dresden; and No. 3, Bavaria, with headquarters at
Munich. After the annexation of Austria, Sector No. 4 was added,
commanded by Gestapo Chief Scheffler whose headquarters are in Berlin
with a branch in Vienna. Sector No. 4 also directs _Standarte II_
which stands ready to provide incidents to justify German invasion
"because the situation has got out of control of the local
authorities."

Another way in which immigration authorities, especially in countries
surrounding Germany, can detect Gestapo agents is by the position of
stamps on the German passport. Stamps are placed, in accordance with
German law, directly under the spot provided for them on the passport
on the front page, upper right hand corner. Whenever the stamps are on
the cover facing the passport title page, it is a sign to Gesta
