‘What’s done is done, and I happen to think it all worked out for the best.’ ‘You do?’ Brian asked. If Trent said a thing was good, Brian would have died defending it, that went without saying, but Laurie had sworn on Mom’s name.

‘Something this weird needs to be investigated, and if we waste a lot of time arguing over who was right or wrong to break their promise, we’ll never get it done.’

Trent glanced pointedly up at the clock on the wall of his room, where they had gathered. It was twenty after three. He really didn’t have to say any more. Their mother had been up this morning to get Lew his breakfast – two three-minute eggs with whole-wheat toast and marmalade was one of his many daily requirements – but afterward she had gone back to bed, and there she had remained. She suffered from dreadful headaches, migraines that sometimes spent two or even three days snarling and clawing at her defenseless (and often bewildered) brain before decamping for a month or so.

She would not be apt to see them on the third floor and wonder what they were up to, but ‘Daddy Lew’ was a different kettle of fish altogether. With his study just down the hall from the strange crack, they could count on avoiding his notice – and his curiosity – only if they conducted their investigations while he was away, and that was what Trent’s pointed glance at the clock had meant.

The family had returned to the States a full ten days before Lew was scheduled to begin teaching classes again, but he could no more stay away from the University once he was back within ten miles of it than a fish could live out of water. He had left shortly after noon, with a briefcase crammed full of papers he had collected at various spots of historical interest in England. He said he was going up to file these papers away. Trent thought that meant he’d cram them into one of his desk drawers, then lock his office and go down to the History Department’s Faculty Lounge. There he would drink coffee and gossip with his buddies… except, Trent had discovered, when you were a college teacher, people thought you were dumb if you had buddies.
