right.”
    “If you would be so good as to bring with you the memory stick from Mr. Adams’s camera and any copies you might have made of the photos he took, that would be terribly helpful.”
    “Of course. No problem.”
    “Finally, please pack clothes and toiletries for a two-night stay at the site.”
    “Site?”
    “The Grady Adams residence.”
    “Why would that be necessary?”
    “We never know. Things happen. Questions arise. I know it’s an inconvenience, but it’s just better if the principals are all in the same place for the preliminary investigation.”
    “We can all gather in the drawing room for a reenactment,” she said, “but there’s no butler, suspicious or otherwise.”
    “That’s funny,” Jardine said with delight but without a laugh. “That really is clever. I’m looking forward to meeting you, Doctor. Please be at the site sooner than later.”
    “I will. Oh, Mr. Jardine. Are you with the National Science Foundation or the Environmental Protection Agency?”
    “Neither, Doctor. This investigation is being run by the Department of Homeland Security.”

Forty-three

W hen Grady woke in the Stickley-style reclining chair shortly before 7:30 A.M ., he switched on the nearby lamp and discovered that the three chums and co-conspirators were not on the bed where he had last seen them. They were nowhere in the bedroom, and when he called Merlin, the dog didn’t appear from either the adjoining bathroom or the closet.
    The door to the hall stood ajar. He was certain that he had closed it before retiring.
    Yawning, scratching his head, he got out of the chair and padded barefoot into the hallway. The doors to the other upstairs rooms were closed.
    Downstairs, in the living room, morning light flooded in through the windows and drew his attention to the items arrayed on the carpet in front of the walnut desk with the hammered-copper hardware and the decorative pewter inlays. The contents of every drawer and shelf in the desk lay in neatly aligned rows: a stapler, a staple remover, a ruler, pencils, pens, a box of rubber bands, a boxof paper clips, a small container of Sortkwik fingertip moistener, a packet of plain white envelopes. …
    The tableau suggested that someone might be conducting a meticulous inventory of his business supplies. Maybe Merlin planned to drive over to the Costco in the next county and needed to compose a shopping list.
    In the hallway, the end door to the kitchen was closed, as was the door to his study on the right. To the left, the library door stood open, and lights were on in that room.
    On the floor were approximately twenty books in three stacks. Grady had not left them there.
    Curious, he knelt to examine the volumes. They were a mix of nonfiction and fiction in various genres. At first he could see no connection between them—and then he realized that all of the dust jackets of all the chosen books had exceptionally colorful spines: red, yellow, hot pink, orange. …
    Because his books were arranged alphabetically, Grady knew that the selection had been taken from both low and high shelves and from half a dozen points around the room. Cold reason suggested he could dismiss from consideration the possibility that Merlin had learned to climb.
    The suspicion arose that he had been prudent to go barefoot and not to announce himself in any fashion since coming downstairs. In the hallway, he listened attentively and heard furtive noises behind the end door.
    Stepping into the kitchen, he found the wolfhound sitting at the open pantry. At first there was no sign of Puzzle and Riddle, but then from the pantry appeared a white furry arm ending in a coal-black hand that offered a Ritz cracker slathered with peanut butter.
    For a dog his size, Merlin routinely accepted any treat with a gentleness that was surprising, taking it with soft lips and quick tongue, never with a rudeness of teeth, finessing it from fingers instead of snatching. He accepted the Ritz cracker with his usual good manners.
    As the dog munched the cracker and lavishly licked his chops, he turned his head to Grady. His expression suggested that henceforth his dad could sleep late every morning while his new best friends whipped up breakfast.
    When Grady peered into the pantry, he discovered Puzzle and Riddle sitting on the floor as they had sat on the sofa the previous evening, not like dogs or even like prairie dogs, but as if they were human children. Their legs were straight in front of
