"I tend to get up around sunrise, run for about a half hour, then work out and train for another hour or so; drop in any morning. Since you're not familiar with magic, you should at least see a demonstration of what magic can and can not do."
"That will be better than guessing blindly," Richard nodded. "And speaking of on call," he pulled a pair of gold coins out of his suit jacket pocket, one ounce gold galleons, "I had hoped you were the real thing and made these up earlier today. The two coins are magically linked. I've keyed one to me." He pushed one of the coins closer to Natasha. "If you let me key the other one to you, when you activate it I can use it as a target to Apparate directly to you without having to have been to the location before."
He shook his head. "The charm is actually on my holster. Magic doesn't tend to work well on things that are metal without a lot of work, especially a permanent spell. There is no free lunch. It can also play hell with unshielded electronics, and in the same way, be disrupted by them sometimes."
