Phryne agrees to pay for the bolt of cotton fabric she uses to escape from the window of the locked salon, which Jack informs her is worth £100. Adjusted for inflation, that would be equivalent to roughly £4,249 today. This is not particularly believable, considering the average house around that time could be purchased for about $2,500 - 4,000 (or approx £8,000), in addition to the fact that there was only enough fabric to leave Miss Fisher dangling above a ground floor door frame.
