If Sheena was going to testify in the eventual murder trial, it would need to be her choice and her choice alone to do so. By putting her on the plane to her home nation, her actual home nation, the Devon police knew that she was under no obligation to ever come back. Up to that point, she'd been aloof and uncooperative at every step.

And now they had every indication that even though the jig was up, she was not about to turn on her father.

And now they had every indication that even though the jig was up, she was not about to turn on her father.

No one knew where her head was at. No one knew what her father had indoctrinated her with. No one knew what she thought or felt or was still trying to hide. And she certainly didn't seem in a hurry to talk to anyone about any of it. I'm Sam Mullins, and this is Sea of Lies, from CBC's Uncover. Episode 6, Sheena.

Bill McDonald took us around the Dart region, the area in Devon along the River Dart, to retrace the steps of Walker and Platt's July 1996.

When the inquiry began, guided by the calls and the cell tower pings of Walker's cell phone, the Devon police began a rigorous door-knocking campaign, all up and down the dart, to see if anyone remembered seeing Ron Platt or Albert Walker that July. Or, better yet, if they'd seen them together.

The details of Ron Platt and Albert Walker's movements in the final month of Platt's life are complicated, but to those building the murder case, essential to understand. The verified timeline of the final month of Ron Platt's life goes like this. In June 1996, Albert and Sheena Walker are living in Woodham-Walter, Essex, and Ron Platt is living nearby in Chelmsford.

The verified timeline of the final month of Ron Platt's life goes like this. In June 1996, Albert and Sheena Walker are living in Woodham-Walter, Essex, and Ron Platt is living nearby in Chelmsford.

Sometime that June, Albert tells Sheena that Ron has moved to France, and Ron Platt's actions that month seemed to support that he did indeed plan to move. Ron gives his notice at the Chelmsford place. On June 21st, Albert helps him move out. They put all this stuff into a storage unit, and then Albert checks Ron into a nearby hotel, where he'll remain for a couple of weeks.

Then, in the first week of July, Albert picks up Ron, and they drive four and a half hours west to Totnes on the River Dart in Devon, where they check into a place called the Steam Packet Inn. Two days later, Albert walks into a nearby yachting shop where he purchased seven items. A jacket, varnish, grease, a length of rope, a roll of green duct tape, a roll of black duct tape, and an anchor.

What was Ron thinking during this time? That he and his good friend Albert were simply having a mini-vacation, a sort of send-off before he moved to France? We don't know for sure. But the police found two women who remember chatting with Albert and Ron in the pub at the Steam Packet the night of July 8th.

The talkative one of the two men told them that they were both divorcees and that they had a plan to sail to France to start a new life. Which brings us to July 9th, 11 days before Ron Platt died. July 9th remains a big question mark, a day that fascinates those familiar with the case to this day.

That morning, Albert and Ron checked out of the Steam Packet Inn after breakfast, got on the Lady Jane, Albert's 24-foot sailboat, and headed out to sea. No one sees them until late that night. At around 11 p.m., Albert calls a hotel in Totnes, one called the Royal Seven Stars, and says, We're on a boat waiting for the tide to come in. Do you have two rooms? They did.
