Ashley glanced at his watch.

“10010 past 1011.”

Jack did a quick calculation. Eighteen minutes past eleven. It was binary, of course, Ashley’s mother tongue. He generously spoke it as ones and zeros for Jack’s benefit—full-speed binary sounds like torn linen and is totally unintelligible. Ashley had no problem with English or any of the other twenty-three principal languages on the planet; it was the decimal numbering system he couldn’t get his head around. He was a Rambosian, an alien visitor from a small planet eighteen light-years away who had arrived quite unexpectedly along with 127 others four years previously. Every single one of the 70 billion or so inhabitants of Rambosia were huge fans of Earth’s prodigious output of television drama and comedy, and Ashley had been part of a mission to discover why there had never been a third series of Fawlty Towers and to interview John Cleese. But when the mission got to see just how much filing and bureaucratic data management there was on the planet, all 128 elected to stay.

Ashley had been in uniform for two years as part of the Alien Equal Opportunities Program and had found himself, after much reshuffling, at the Nursery Crime Division, where he could do no serious harm. His real name was 1001111001000100111011100100, but that was tricky to remember and even harder to pronounce. Get the emphasis wrong on the seventh digit and it could mean “My prawns have asthma.” He was about five feet tall with slender arms and legs that bent both ways at the elbows and knees. His head was twice the width of his shoulders, with big eyes, a small mouth and no nose. The UFO fraternity had got an alien’s appearance pretty much right, which surprised them all no end. His police uniform had been especially tailored to fit his unique physique, with a special elasticized girth, as Rambosians had a tendency to swell and contract depending on atmospheric pressure.
