So it was not a good time to reminisce about Drake. Daniel swiveled the Reflecting Telescope around until the ragged plume in the horseman's hat showed up as a bobbing white blur, like the tail of a hustling rabbit. Once he'd focused on that, a couple of tiny adjustments brought Isaac's waterfall of argent hair into view – just in time, for he was ascending a few steps into a building across from the Haymarket, along the convergence of traffic that eventually became Pall Mall. Daniel played the telescope around the front of the building, expecting it to be a coffee-house or pub or inn where Isaac would await his gentleman friend. But he was completely wrong. To begin with, this place was apparently nothing more than a town-house. And yet well-dressed men came and went occasionally, and when they emerged, they (or their servants) were carrying packages. Daniel reckoned it must be some sort of shop too discreet to announce itself – hardly unusual in this part of London, but not Isaac's sort of place.
