The widow of wine merchant Robert Adams remains in the dark about the circumstances of his death more than a month after he apparently fell overboard on a Central to Lamma ferry. 'Maybe no one saw what happened,' Heather Adams said. 'But I find that hard to believe. He was very happy - definitely not suicidal - and to my knowledge had no enemies.' Neither ferry staff nor passengers seem to have seen what happened to Adams on the night of September 9. Police are investigating the case, but appeals for witnesses, including the posting of Adams' picture around Lamma, have been in vain. 'Initial investigations revealed no suspicious circumstances and no witness was located,' police said. 'We have no idea what happened to Mr Adams,' Hong Kong and Kowloon Ferry (HKKF) spokesman Sam Lau said. On September 9, a typhoon was brewing and the sea was rough. The day was coming to a close and Adams, 45, who worked for Kedington Wines in Chai Wan, was just wrapping up a business meeting in Central. Footage from HKKF's closed-circuit television (CCTV) shows him boarding the 9.30pm ferry, the Sea Star. He was wearing a bright blue shirt and tie, black trousers and black shoes, A friend later told Mrs Adams he saw her husband sitting at the front of the downstairs cabin, engrossed in his book, Pax Brittanica. Adams was wearing his light-sensitive spectacles, which often looked dark. Deciding not to disturb him, the friend went upstairs. At 9.40pm, Adams phoned his 49-year-old wife, saying he was on the ferry and should be home shortly. Home was Pak Kok village, a 20-minute walk from the Yung Shue Wan ferry pier, so she was expecting her husband home at 10.30pm. The couple originally came from Buckinghamshire in southern England but had lived on Lamma for eight years. They have no children, though Mrs Adams, an art teacher, has a grown-up daughter from a previous marriage living in Britain. When her husband did not show up as expected, Mrs Adams thought he probably was out having a drink with a friend in Yung Shue Wan. When midnight struck and there was still no sign of him, she tried to call him on his mobile phone but it just kept ringing. 'It was odd. I'd bumped into him that afternoon in Central and he'd said he was looking forward to getting home early,' she said. At 6am on the Tuesday, after a sleepless night, Mrs Adams called police. Shortly afterwards, an HKKF representative rang to say her husband's black briefcase had been found on board. 'That freaked me. I felt then he was in the sea. My gut feeling was that the worst had happened because I knew he'd caught the ferry,' she said. Early that afternoon, the marine police phoned to say a body had been found in the harbour off Kennedy Town. At the morgue, a coroner's staff member told Mrs Adams that the marks on her husband's body were 'consistent with having been in the water and bumped against rocks'. Results of the post mortem examination will be released at the inquest. Police said no one seemed to have noticed Adams leaving his seat or going out to the open deck. Mr Lau, the HKKF spokesman, conceded that the Sea Star's small, open-deck toilet area was only partly visible from the downstairs cabin, but he added that since the incident, the vessel had passed a Hong Kong Marine Department safety check. Existing CCTV cameras, he added, were focused on the engine room and the berthing area. He said there was no need to install one on the outside deck.
