Halford Lovell Boudewyn (1921 – 26 April 1998) was a Singaporean retired police officer who, during the Japanese occupation, worked as a spy by stealing classified document from the Indian National Army (INA) and shared war news about the Japanese to prisoner-of-war camps using an illegal wireless set.

Born in 1921, Boudewyn studied at St. Joseph's Institution and graduated and joined the Straits Settlements Police Force in September 1939.

While supplying food, he became friends with a British Indian Army officer, Aubrey Wyman,[2] who was a prisoner-of-war (POW).

[1] By then, the documents were located in a different camp and Boudewyn quit his job to join the then-Japanese controlled police force.

Unexpectedly, the Japanese decided to occupy the house, turning the spot where Boudewyn had buried the oil drum into a garden.

[8] On 26 April 1998, Boudewyn died in his sleep at 77 after suffering from bladder cancer for 12 years and severe heart complications.
