He stopped, noticing my gaze.

“He’s standing right behind me, isn’t he?” Xavier murmured.

“Uh-huh.”

Xavier tilted his head back, saw Clay and disappeared. He reappeared on the opposite bench, pressed up against me. I looked over at him, eyebrow raised. He swore under his breath and teleported to the far end of the other bench. Then he stood and turned to Clay.

“You must be-”

“The fucking psychopath,” Clay said.

“Er, right, but I meant that in the most respectful way. Believe me, I have the utmost regard for, uh…”

“Raging lunatics,” I said.

Xavier shot me a glare.

“Oh, sit down,” I said. “He didn’t bring his chain saw.”

Clay circled the table and slid in next to me. Xavier waited until he’d sat, then took his original place across from me.

“Clay, this is Xavier, Evanidus half-demon. Specialty? You just got a little demonstration of that.”

“A pretty damned indiscreet demonstration,” Clay said, shooting a look over at the playground.

“No one saw,” Xavier said. “And even if they did, they’ve already explained it away. Humans only see what they expect to see. I bet you guys could change into wolves right here and you’d have twenty parents grabbing their cell phones-not phoning CNN to report a werewolf sighting, but calling the Humane Society to pick up a couple of really big dogs that are definitely violating the leash laws.”

“Speaking of violating leash laws, you do know where David Hargrave is, right? And he’ll still be there when we arrive?”

“He should be. If he bolts, it won’t be because I tipped him off. And if he does bolt, I’ll get you a new location or you don’t owe me a thing. This guy killed three women. I say you’re welcome to him. I may not be the most moral guy, but with something like that, I’ll gladly turn him in to the proper authorities. Which, in this case, would be you guys.”

Clay snorted. “How long have you known where he was before your sense of civic duty kicked in?”

“Let me guess,” I said. “Just long enough to find something you could ask for in return. Don’t give me the wounded look. We want Hargrave. What do you want?”

Xavier eased back in his seat. “You guys ever hear of the From Hell letter?”

“No, and from the sounds of it, I’m not sure I want to.”

Clay said, “If this is some kind of demon thing, we’re not interested. The werewolves don’t get involved in-”

“It’s nothing demonic. It’s just a letter. Supposedly sent by Jack the Ripper to the police. At some point over the next hundred years, it went missing.”

I frowned. “You want us to find-?”

“Oh, I know where it is. It was never really missing. Not to our side of the world, that is.”

When Clay and I glanced at one another, Xavier rolled his eyes. “Our side. The supernatural side. You guys rejoined the council; that puts werewolves back in the middle of the whole supernatural community. Didn’t you get your membership cards?”

“About this letter,” I said.

“All the Jack the Ripper files were sealed up for a hundred years. When they were opened in the eighties, the From Hell letter was missing. Not surprising, considering it was stolen back in the twenties. The theft was commissioned by a sorcerer.”

“Why? Is it magical?”

“Nah. The only way of getting it was with supernatural aid, so it stayed on our side of the line. But just think-that letter could tell us the true identity of Jack the Ripper, and some rich spellcasting son of a bitch is hoarding it for himself. Disgraceful. We are about to rectify that.”

I glanced at Clay. “Not liking the sound of that ‘we.’ ”

“Me neither,” Clay said.

“I hope you aren’t going to ask us to steal that letter-”

“You can’t steal stolen goods. What I’m asking is for you to right a very old wrong.”

“And return it to the London Police. Gee, that’s mighty big of you, Xavier.” I turned to Clay. “See, there is a sense of civic duty there after all.”

“Ha-ha. I’m passing it on to a buyer, yes, but he wants to have it analyzed by a team of DNA experts so the world can know once and for all the identity of Jack the Ripper.”

“Damn,” I murmured. “That is a righteous cause. Now we can finally catch that murdering bastard and lock him up in prison where he belongs.”

Before Xavier could open his mouth, I continued. “What’s the guy looking for: a book deal or a movie deal?”

Xavier hesitated, then said, “Book…and probably movie eventually, but he’s investing over a hundred thousand dollars in this crusade-”

“In return for a book deal that I’m sure will net him a pittance.”

I glanced at Clay. He shrugged. He was right. As offensive as I found this guy’s reason for wanting the letter, it wasn’t doing anyone any good where it was now. And we needed to find David Hargrave before he went on another killing spree.

“Why us?” Clay said. “You can teleport through walls.” He met Xavier’s gaze. “Unless there’s a reason you want someone else to do it.”

“There is, but not the one you’re thinking. There’s zero danger involved. No electric fences or armed guards. Just a spell. A very special spell. That’s how it was protected the first time too, probably by a sorcerer judge or prosecutor who wanted to keep all the Ripper letters safe, so he cast a spell that would detect any living being who came near them. To get the letter, then, the guy who wanted it stolen found himself a very special thief, one without that telltale beating heart.”

“A vampire,” Clay said.

“Whoa. You’re good. When he got the letter, he cast another protection spell around it-one that will detect anything in human form. He figured that was safe. Sure, someone could send in a specially trained bird or whatever, but no bird could open the sealed glass box.”

“Ah,” I said. “So, to retrieve it, you need someone not in human form. A wolf, perhaps.”

“You got it.”

I leaned forward. “Problem number one: as you doubtless noticed back at the compound, we change into full wolves. Wolves with paws. Operating a glass cutter? One of those things that requires opposable thumbs.”

“True, but as I also recall from the compound, you can change just your hand.”

“From human to wolf, yes. Vice versa? Not so simple.” I glanced at Clay, who gave a half-shrug. “Not impossible, but not easy either. How many locks are we talking? Is the box locked or just sealed? And I assume the room is locked too?”

“The box is just sealed-a solid glass box bolted to the table. As for the door to the room, it’s locked, but more to keep out the housekeeper than serious thieves. The spell covers that. Once you get the door open, you just need to change forms before you get too close to the glass box. As for changing just your hand back, that’s pretty much essential. Change any more and you’ll set off the alarms, so if you can’t-”

Clay cut in. “We’ll deal with it. Bigger problem for me? What’s to say this sorcerer hasn’t used both the spells: the one to detect a pulse and the one to detect human form?”

“Can’t. If you double up high-powered spells like that, you’re almost guaranteed nasty side effects. Don’t take my word for it, though. Check it out with your spellcasting buddies. Either this sorcerer didn’t think about werewolves, like the last one didn’t think about vampires, or he figured there was no real risk. Vamps are known for stealth, weres for killing.”

“So this letter is in Toronto?” I said.

Xavier nodded. “Owned by the grandson of Theodore Shanahan, the sorcerer who had it stolen from the police archives. Guy’s name is Patrick Shanahan. Lives alone. Typical investment banker-keeps his life very ordered and dull, with a strict routine. You won’t show up and find he’s moved the letter or skipped a client dinner to stay home unexpectedly. If he does? Abort, and we’ll try again. No rush. No pressure. This letter isn’t going anywhere.”
