Why does Laura says she had to pretend for four years?
In "In the Steele of the Night", Murphy said it had been four years since they'd left Havenhurst Detective Agency. Since Laura had her own agency for six months, she could not have been pretending for more than 3.5 years
Of course, 3.5 and 4 are pretty close, Laura could be merely exaggerating a bit, considering her mind is completely elsewhere at the moment.
But it still contradicts with "Red Holt Steele", in which the goons at Varicorp said she had been employed with Remington Steele Investigations for the last 3.5 years, and "Forged Steele", in which Laura calls Remington Steele Investigations the product of six years of hard work; both mean there was no Remington Steele in the picture for only 2.5 years.
Still, four is a new number.
It also contradicts with what Laura says in the coffin in "Dreams of Steele" about "three years of building up the agency," which means no more than a year and a half without Remington Steele in the picture.
