The phone rings in dr steins house

It’s 10 pm when the phone rings in An Elderly Dr. Stein’s house.

“It’s Dr. Gold,” says his wife, passing him the phone,

“I do hope it’s not another emergency.”

Dr. Stein takes the phone and says,

“Hi, what’s up?”

“Don’t worry, everything’s OK,” replies Dr. Gold.

“It’s just that I’m at home with Dr. Lewis and Dr. Kosiner. We’re having a little game of poker and we’re short of one hand so we thought you might like to come over and join us?”

“Sure …. yes, of course,” replies Dr. Stein, putting on a serious voice,

“I’m leaving right now.”

And he puts down the phone.

“What’s happened?” his wife asks, with a worried look.

“It’s very serious,” Dr. Stein replies.

“They’ve already called three doctors.”
