Mary had excused herself on the plea of an engagement with Dr. Bauerstein.
We had a pleasant luncheon, and as we drove away Lawrence suggested that we should return by Tadminster, which was barely a mile out of our way, and pay a visit to Cynthia in her dispensary. Mrs. Inglethorp replied that this was an excellent idea, but as she had several letters to write she would drop us there, and we could come back with Cynthia in the pony-trap.
We were detained under suspicion by the hospital porter, until Cynthia appeared to vouch for us, looking very cool and sweet in her long white overall. She took us up to her sanctum, and introduced us to her fellow dispenser, a rather awe-inspiring individual, whom Cynthia cheerily addressed as "Nibs."
"What a lot of bottles!" I exclaimed, as my eye travelled round the small room. "Do you really know what's in them all?"
"Say something original," groaned Cynthia. "Every single person who comes up here says that. We are really thinking of bestowing a prize on the first individual who does not say: 'What a lot of bottles!' And I know the next thing you're going to say is: 'How many people have you poisoned?' "
I pleaded guilty with a laugh.
"If you people only knew how fatally easy it is to poison some one by mistake, you wouldn't joke about it. Come on, let's have tea. We've got all sorts of secret stories in that cupboard. No, Lawrence--that's the poison cupboard. The big cupboard--that's right."
We had a very cheery tea, and assisted Cynthia to wash up afterwards. We had just put away the last tea-spoon when a knock came at the door. The countenances of Cynthia and Nibs were suddenly petrified into a stern and forbidding expression.
"Come in," said Cynthia, in a sharp professional tone.
A young and rather scared looking nurse appeared with a bottle which she proffered to Nibs, who waved her towards Cynthia with the somewhat enigmatical remark: "I'm not really here to-day."
Cynthia took the bottle and examined it with the severity of a judge.
"This should have been sent up this morning."
"Sister is very sorry. She forgot."
"Sister should read the rules outside the door."
I gathered from the little nurse's expression that there was not the least likelihood of her having the hardihood to retail this message to the dreaded "Sister".
"So now it can't be done until to-morrow," finished Cynthia.
