 can use, but this is a lot more specific than a random fight with the Master's goons."

"I don't suppose you can just enter 'find dial', can you?"

He turns his dial so that I can see the face-. It has four letters, 'H', 'E', 'R' and 'O'.

"Bobby's Wizard personality didn't want any chance that we'd misuse it or dial something we weren't supposed to."

Mr Hamill clenches her fists in frustration. "I still say I should try using that to turn back. I just gotta dial 'hero' again, don't I?"

Mr King shakes his head. "Assuming it still works the same, you gotta dial 'oreh'."

"Huh?"

"It's 'hero' backwards. And honestly, given the crazy stuff these dials can do, I wouldn't risk it."

Richard looks up at Mr Hamill. "How about we try it if Mr King's dial can't find it?"

Mr Hamill droops. "This whole day's sucked. I just want it to be over."

Mr King looks at him sympathetically for a moment, then raises his left wrist. Looks like his dial is built into his wristwatch. Now that's worrying. The potential for concealed usage… "Okay, here we go with attempt number one. 'H-E-R-O'."

There's a faint white-yellow glow as Mr King recedes and another figure comes to the fore. Some sort of… Bizarre parody of Sherlock Holmes, complete with deerstalker-mounted magnifying glasses.

"Super Sleuth, master of mysteries and concluder of conundrums!"

He takes a moment to look himself over.

"Which would be great if we had any evidence to work with, but the first deduction I'm going to make is that if no one knows where it went there aren't going to be clues in human behaviour and you've already searched all of the reasonably probable locations for it to wash out. O-R-E-H."

Mr King reappears and redials.

"H-E-R-O."

This time he gets a.. vaguely animalistic alien, with.. antennae and blue skin.

"The Transphasic Tracker. This should work! Okay, I'll need to head back to the bridge, then I should be able to follow exactly where it went!"

My team mates look at one another in confusion. Raquel shakes her head.

"What'd he say?"
