Sixth in the series, but all of them work fine as standalones. McDevitt follows his usual formula although this time there are no humans attempting to kill off Benedict and Kolpath. Nice mystery, fun puzzle-solving, with maybe an eyebrow lift that any talk show, let alone several, would be interested in the debate betwen an antiques dealer and a museum curator about an obscure physicist. Perhaps in McDevitt's world, this is the most pressing topic - what a nice thought. The AI debate is very interesting and I'm sort of surprised about Benedict taking the position he did. Anyway, nice snappy reading and good world-building.
