Croiset was said to
be a psychometrist - a person who can
read information from a held object. He
said he became aware of this gift while
a youth working for a watch repairer.
On one occasion he held a ruler
belonging to his employer and saw
events which he related to his employer
and which his employer confirmed were
accurate.
After
World War II, Croiset was sometimes
consulted by Dutch police authorities
in cases involving missing persons, or
murder. On one occasion he was said to
have examined the property of a
murdered woman, and provided accurate
information relating to her murder, and
also gave the name of her murderer. The
name matched a man who was being held
in connection with the crime. He gained
a reputation as a reliable consultant
in the area of missing persons, and his
fame extended beyond the Netherlands,
as anecdotes about his abilities came
to be discussed in other
countries.
He also
gained a reputation as a healer, and
would allow people to visit him in his
clinic for healing sessions. In 1966 he
was invited to Australia to aid in an
investigation relating to the
disappearance of the three Beaumont
children, who had disappeared without
trace from a beach in Adelaide, South
Australia. Although police were
sceptical, his expenses were paid by a
wealthy businessman interested in the
case, and public pressure was such that
Croiset's views were
considered.
During
his short stay in Australia he
attracted widespread publicity but
failed to find any trace of the missing
children. In the mid 1970s he was
invited to Puerto Rico to find the two
missing children of a local
businessman. He concluded that the
children were no longer on an "earthly
plane" and could offer no clues. Also
around the same he was called upon to
locate a missing woman in Scotland, and
once again failed to provide any
clues.
His
reputation became tarnished in his
later years by his well publicised
failures. However he achieved one more
notable success when invited to Tokyo,
Japan in the 1970s to locate a missing
child. Within 24 hours he had provided
a description of the location in which
her body could be found, and when her
body was found after following his
instructions, all details seemed to
match exactly with his
prediction.
