Apart from it involving a close friend, it was the kind of case that interested me. Also the kind you had to work hard at to get a result. A money-spinner, but I didn't want to bleed Frank.

The Heysen house was a big, sprawling affair on a corner block overlooking the Cooks River and a stretch of green beyond that. The water view wouldn't have been an asset in days gone by when the Cooks River was more or less a sewer cum toxic waste dump, but it'll become more acceptable as the river gets rehabilitated. Long way to go. The government is said to have promised the money, but nothing much seems to be happening. With half a million people living along the river's banks, I suppose cleaning it is a big ask. There were more apartment blocks in the locality than freestanding houses.

I parked in the street and looked the place over more closely. It was far too big for a woman and a child as things must have stood when Dr Heysen went inside. Probably they'd planned a large family. Still, I wondered why she hadn't traded it in on something more manageable.

I could see a large garden in front and down the side, through an electronically controlled gate, a wide driveway. There was enough grass to keep a Victa busy for an hour or so. The corner block was deep, so there was probably more garden and grass at the back. Quite a few tall trees graced the scene, no doubt harbouring birds and cicadas, but also likely to drop leaves into the guttering. Okay for the doc who could afford to hire help, but what about the widow?

Frank's notes on her were minimal, as if he couldn't bear to think about her too much. She was forty-six now and had been a dental nurse before her marriage to Heysen at age twenty-two. Her father had been a champion cricketer and an executive in a large sporting goods firm. I had no information on her mother or on whether either of her parents was still alive. Given her age it was more than possible. Then again, if they'd died asset-rich, maybe she'd inherited the means to keep this big joint going.
