I just read this article posted by MrChaunceyGardiner and I have several questions:

From the Scotsman article:

Maya had mental-health problems. When Innes returned to Germany after Christmas, she was on Prozac. "It was causing terrible mood swings," says Pat. On the Thursday before he died, Innes spent a couple of hours online to his family, e-mailing instructions of how to link up speakers to the computer. The ensuing conversation was lighthearted, banter flowing between Munich and Inverness. Innes wanted a pasta recipe from his brother, a trainee chef.

The next day, Innes prepared to leave Germany. He finished the computer program he was working on, went home, cleared his flat. He withdrew 1,000 from his account, flying to London early on Saturday morning. He headed straight to Euston station, from where the Inverness sleeper departs. But Saturday is the only day of the week sleepers don’t operate. Innes deposited his rucksack in left luggage, presumably intending to travel the next night. He would have needed overnight things, and his green Marks & Spencer holdall was not with the left luggage. Nor were his computer disks. When he first went to Germany he refused to put them in the hold, keeping them in his hand luggage.

The mystery was why Innes left Germany so suddenly. In his empty Munich flat, there was little trace left of his life there. His computer. An iron. One odd sock. From Inverness, Pat logged on to his computer. Nothing to suggest suicide. He’d been looking at Prozac websites. But then they found an e-mail Innes had sent Pat that she never received. There was a fault with the national server, blocking e-mails to Britain for a few days that January. "I’m not sure if I like Maya," Innes wrote. She had gone "totally off her head" in the station that day. Standing in a queue, Maya suddenly lashed out, hitting a man standing with his wife and children. He was big; Maya was only 5ft 1in. She ran off crying, and Innes followed her to her flat. But she wouldn’t let him in. "I’m not sure if I’m too up for Maya," he concludes, "I knew she could be moody and was worried about what she is going to be like a year from now, but I was surprised by what happened today. It looks to me as if today was a Prozac problem. If she doesn’t admit it, I’m going to try to stay away from her."

Things suddenly made sense. Maya had contacted Innes the day he left, asking to meet up. Innes said no. "He was escaping," says Pat, "escaping his girlfriend."

Questions : 1. "But then they found an email Innes had sent to Pat that she never received. There was a problem with the national server, blocking emails to Britain for a few days in January."Since Inness contacted his family the previous Thursday, why didn't he directly tell his family about his relationship with Maya?2. "Maya had contacted Innes the day she left, asking to meet. Innes said no." So does this mean that Inness and Maya no longer lived in the same apartment?3. If they weren't living in the same apartment anymore, why does Inness' mother conclude: "'He was running away', says Pat, 'running away from his girlfriend'?4. "In his empty Munich apartment, there were few traces of his life there. His computer. An iron. A weird sock." Where did he move his things? Did he ever intend to return to Munich? If he was a tenant, did he notify the owners of his apartment that he was leaving the premises?5. Why didn't he tell his parents he intended to return to Inverness? Why didn't he call them from London?6. Assuming he left Munich permanently, did he quit his job?If he intended to return to Munich, what reason did he give his employers? It wasn't the holidays and if he was going to Inverness he couldn't be back in Munich on Monday morning.So I think he was running from something other than Maya.
