Arne was born in Kuala Lumpur, British Malaya, to a Swiss-French mother and an American father, and gained his early acting experience in British provincial repertory. In 1953, the New Lindsey Theatre Club performed his play No Stranger.[4]
From the mid-1950s onwards, he developed a successful career playing a broad range of supporting roles in both film and television often with a specialisation in playing unsmiling villains and German officers. In addition to acting, he ran his own antiques business.[5]
In 1968, he played the roles of the prisoner known as the Duke, as well as Dr. Sanson Carrasco, in the London stage production of Man of La Mancha. (The two roles were played by John Castle in the 1972 film version of the musical.)
In the 1960s and 1970s, Arne was a busy character actor on television. He appeared in several ITC adventure series and in four episodes of The Avengers as different characters each time. He was also in The Protectors in 1972. He appeared in the last two episodes of Secret Army (1979) as a German Colonel, and as a regular in series two of Triangle in 1982.[6]
In the late 1940s, Arne and his partner at the time, Jack Corke, befriended English novelist Mary Renault and her partner, Julie Mullard, on the SS Cairo, a steamer bound from Britain to South Africa.
Arne (aged 26 at the time) and Corke persuaded Mary Renault that they could get rich quickly by building housing for recent immigrants like themselves. The four of them established a company called CAM Construction, which Renault financed using a £25,000 award she'd received from the movie studio Metro-Goldwyn-Mayer, and the company began employing labourers and craftsmen to begin construction of several houses.
Arne and Corke (an alcoholic) squandered funds on high living, leaving bills unpaid, and the company failed to generate revenue. After Arne and Corke stole Renault's Studebaker, her lawyer obtained their resignations from the firm and persuaded them to leave the house the four had formerly shared. Arne and Corke then disappeared from Renault's life for good, Arne returning to Britain.[7]
On 1 August 1983, Arne attended a costume fitting in Clerkenwell intended for his character Range in the BBC Doctor Who television serial Frontios (a role which would eventually be played by William Lucas).
Shortly after Arne returned to his Knightsbridge home, neighbours reported hearing a violent argument coming from his home. Arne was later found inside his flat, bludgeoned to death[8] with a stool and a log from his fireplace, which was found in the communal hall.
The prime suspect in Arne's murder was a schoolteacher from Verona, Italy, who had been living rough in a local park, and for whom Arne had been providing food.
Police issued a photofit image after eyewitnesses reported seeing a young man loitering nearby eating a jar of honey. Four days later, a body matching this description was found in the River ThamesatWandsworth, having drowned in an apparent suicide. Bloodstained clothes were later found upstream at Putney.[9] Police identified the body as that of Giuseppe Perusi, an Italian schoolteacher. Inquiries revealed Arne had been giving food to the Italian man.
Aninquest at Westminster Coroner's Court in October 1983 recorded a verdict of unlawful killing for Arne and suicide for Perusi. Police concluded that Perusi had beaten the actor to death then killed himself. The reason for the violent argument and the motive for the killing remain unknown.[10]
