ONE day there was a pile of ashes a couple of feet away from the bottom step [of the back door my house]. It was quite a considerable size. It was really strange.

I looked at it long and hard and racked my brains. I wondered: "Why the hell’s there a pile of ashes at the back door?"

Tracy came into the kitchen and noticed it immediately too. She asked: "What's that?" I didn't want to distress her so I dismissed it.

Glasgow Times:

I said: "It'll just be from the barbecue. The wind will just have caught it." But it definitely wasn't. I am convinced it was a message, a warning, from somebody. To this day, I have no idea who.

It wasn’t the only unsettling thing which happened. We lived in a quiet little cul-de-sac. One day I was coming back and I met our neighbour who had been out walking his dog.

He said: "Who were the guys up looking for you at four o'clock this morning?"

I replied: “What are you talking about?

"There were three transit vans here early this morning. I got up because the dog was barking. There were guys pointing at the house. Who’ve you upset?"

"I haven't upset anybody."

"Well, they weren't here looking for me."

It was quite worrying. I didn't know who it was. Somebody we were shouting abuse at on match days? Fans who didn't like what we were doing? Somebody whose job was under threat? Heavies who had been sent to put the frighteners on me? I don't know. It certainly wasn’t as a result of anything else I had done in my life. I felt at the time it was done to scare me. It was somebody saying: "We know where you live."

I have two old friends who have associates who are, to put it delicately, slightly off-centre Glasgow businessmen.

Glasgow Times: Craig Houston of the Sons of Struth

They each revealed to me independently of each other that my name was being bandied about in some fairly serious circles. By all accounts, the message being put out was: “This boy should keep his mouth shut or he’ll end up getting a doing.”

I was told: "People have been asking questions about you. The sort of people you don’t want to be getting on the wrong side of.”

That made me sit up straight with a jolt. It wasn't as if I was wearing a bullet-proof vest and looking over my shoulder as I walked down the street.

But I was certainly told: "People are asking about you, wanting to know where you lived." It just verified what I suspected at the time. That certain individuals were unhappy.
