The coach house attic has a studio skylight at one end, an Ottoman couch, a chaise longue, a plasma TV, and an IKEA kitchen table that once took me and Molly three bloody hours to assemble. I’d used the Folly’s status as an Operational Command Unit to get the Directorate of Information to cough up half a dozen airwave handsets with charging rack and a dedicated HOLMES 2 terminal. I also had my laptop and my backup laptop and my PlayStation—which I hadn’t had a chance to get out of the box yet. Because of this there is a big sign on the front door that says NO MAGIC ON PAIN OF PAIN. This is what I call the tech-cave.

The first thing I got when I booted up was an email from Leslie with the header Bored! so I sent her Dr. Walid’s autopsy report to keep her occupied. Then I opened up Police National Computer Xpress and ran a DVLA check on Melinda Abbot’s license plate and found that the listed information matched that on her driver’s license. I ran Simone Fitzwilliam as well, but evidently she’d never applied for a license or owned a car. Nor had she committed, been the victim of, or reported a crime within the United Kingdom. Or possibly all that information had been lost, inaccurately entered into the databases, or she’d just changed her name recently. Information technology only gets you so far, which is why coppers still go around knocking on doors and writing things down in little black notebooks. I Googled them both for good measure. Melinda Abbot had a Facebook page as did a couple of people with the same name, but Simone Fitzwilliam had no obvious Internet presence at all.

I worked my way through Dr. Walid’s list of dead jazz musicians—all men, I noticed—in much the same way. They’re always doing clever cross-referencing stuff on the TV, and it’s all perfectly possible, but what they never show is how sodding long it takes. It was pushing midnight by the time I got to the end of the list and I still wasn’t sure what I was looking at.

I took a Red Stripe from the fridge, opened the can, and had a swig.

Definite fact number one: Each year for the last five, two or three jazz musicians had died within twenty-four hours of playing a gig in the Greater London area. In each case the coroner had ruled the death either “accidental” by way of substance abuse or by natural causes—mostly heart attacks with a couple of aneurysms thrown in for a bit of variety.
