Inside Malcolm's coat pocket, his phone starts to ring. He pulls it out to check the caller ID. A blocked number. Normally that means it's his father calling from Claremont. Malcolm doesn't have time to deal with him right now.

"Hello?" he says, turning away from Sherlock so that he can concentrate on the call.
