She found employment in a few menial jobs before becoming a prostitute on the streets and, not drinking, smoking or taking drugs, was able to save enough money to buy a large freehold Victorian end-of-terrace house in Earls Court.

For many years from the mid-1970s until her bankruptcy in 1992 (after the Inland Revenue pursued her for tax evasion),[6][7] St Clair offered sexual services from her own large four-storey house at Eardley Crescent in Earls Court, London.

In June 1991 she was involved in a controversy when Norman Lamont, the then Chancellor of the Exchequer, was investigated for using taxpayers' money to handle the fall-out from press stories concerning 'Miss Whiplash' (Not Lindi St Clair), who was using a flat he owned (the Treasury contributed £4,700 of the £23,000 bill which had been formally approved by the Head of the Civil Service and the Prime Minister).

[19][better source needed] She accused the Inland Revenue of trying to live off immoral earnings when they asked her to pay £112,779.92 in back income tax, because they classed prostitution as a trade.

"[21] On 27 February 2009 it was reported that St Clair had been rescued from her car and flown to hospital after the vehicle left a Herefordshire road near Risbury and landed upside down in a stream, trapping her for up to 24 hours.
