out of the limelight. Jephson recalls that the atmosphere at Kensington Palace at the time was "like a slowly-spreading pool of blood leaking from under a locked door." Throughout 1991 and into 1992, Diana had been secretly collaborating with a previously little-known court correspondent, Andrew Morton, on the book Diana: Her True Story, which revealed in graphic detail the previously hidden disaster that the Waleses' marriage had become. Diana's bulimia, suicide attempts and self-harm were spelt out unambiguously, as were Charles's relationship with Camilla Parker Bowles, and the intrigues of Palace officials in attempting to contain the disintegrating royal marriage. Analysis of the tape In 1993, The Sunday Times published the findings of an analysis of the "Squidgygate" tape, commissioned from Corby-based surveillance specialists Audiotel International. Audiotel concluded that the presence of data bursts on the tape was suspicious. Data bursts ("pips" at intervals of approximately 10 seconds, containing information for billing purposes) would normally be filtered out at the exchange before Cellnet transmission. That these "pips" were present at all was therefore anomalous, but they were also too fast, too loud, and exhibited a "low-frequency [audio] 'shadow'," implying "some kind of doctoring of the tape," said Audiotel's managing director, Andrew Martin, in his firm's report. "The balance of probability suggests something irregular about the recording which may indicate a rebroadcasting of the conversation some time after the conversation took place." Within a week of the Sunday Timess announcement, a further independent analysis was carried out for the same newspaper by John Nelson of Crew Green Consulting, with assistance from Martin Colloms, audio analyst for Sony International. Their analysis demonstrated convincingly that the conversation could not have been recorded by a scanning receiver in the manner claimed by Reenan. Amongst several relevant factors, there was a 50 hertz hum in the background of the "Squidgygate" conversation together with components in the recorded speech with frequencies in excess of 4 kHz. Neither could have passed through the filters of Reenan's Icom receiver or indeed have been transmitted by the cellular telephone system. The 50 Hz hum was consistent with the effect of attempting to record a telephone conversation via a direct tap on a landline. Since Gilbey was known to have been speaking from a mobile phone, inside a parked car, this left Diana's telephone line at Sandringham as the source of the recording.
