Chapter 59: Half Past Five
The card is laminated and it is screwed to the inside of the second-floor linen room door.
NURSERY — DAILY. Eleven items, numbered, in the housekeeper’s typing.
I have walked past that card several hundred times and read it perhaps twice.
On Tuesday morning I stood in that doorway during my hour and read item six.
Humidifier: empty, rinse, refill to line with cold water, replace lid. Turn-down.
Turn-down on the second floor is half past five.
Underneath the card there is a hook and on the hook there is a folder, and in the folder there are the stock cards.
I got four minutes with it while Miss Devlin was warming a bottle,
and I did not touch anything but paper.
Here is what half past five means, and it took me two days to assemble it.
Whoever does the second-floor turn-down empties the tank into the nursery bathroom basin.
They rinse it. They fill it from the tap, with a white plastic jug that lives under that basin.
The jug holds two point three liters.
It takes two jugfuls to reach the line and the second one is not full.
Lid on. Back on the base. Switch left at two.
The timer does the rest at six.
Twelve minutes, start to finish,
and I have done it myself perhaps two hundred times.
Who did it, between March and the thirteenth of October.
Kelsey, five days a week. Roz, on Kelsey’s two days off.
Me, on any evening I was in that room at half past five, which was most of them until the sixteenth of September.
Three people. All three of us named on a card, in a folder, on a hook, for anybody to read.
That is what a turn-down is. It is the least secret activity in an entire building.
And it happens at half past five, which is four hours before the corridor goes quiet.
Everything I had been thinking for two days had been about the corridor at midnight.
The corridor at midnight is not when the tank is open.
Half past five is when the tank is open.
Both are true. I wrote both down and drew a line between them and looked at it for a long time.
If you want water in a tank you can do it at half past five with a jug, in front of anybody, as part of your job.
Or you can do it at any hour you like, because the lid takes one second and the machine runs until five in the morning.
I could not eliminate either. I have never been able to eliminate either.
Then I turned the stock card over, because the back of a card is where the boring information lives.
Demineralization cartridge. Replaced monthly. One line per replacement, with a date and initials.
2 June. 4 July. 3 August. 2 September.
Four lines, four sets of initials,
all of them the housekeeper’s, all of them in the same blue pen.
And then a fifth line.
6 October.
Twenty-four days after the fourth, which is three weeks and three days early, and out of cycle for the first time in the year.
And no initials at all.
It is the only blank in that column on either side of the card.
I stood in a linen room with a folder in my hands and read that line about nine times.
A cartridge sits inside the tank, under the water, for a month.
Whatever is in that water goes through it and stays in it.
If somebody changed it early, the old one left that building on the sixth of October in a kitchen bin.
Twenty days before I ever lifted the lid.
I am not going to write down what I thought that meant, because I have made that mistake in this account once already.
I wrote what was on the card. Date, no initials, out of cycle. Nothing else.
Then I put the folder back on the hook with the flap facing the same way and went back into the room.
He was standing at the low shelf with a book in each hand and could not decide.
He solved it by putting one on the floor and pointing at the other, which is a system.
At twenty to eleven he came and leaned his forehead against my knee for a while, which is new since the cast came off.
I counted six people who walk down that corridor between six and half past nine on an ordinary evening.
Miss Devlin. Mr. Foyle. Roz, twice. Kelsey.
Mrs. Blackwood, who says goodnight to him at the door and does not go in.
And Serena Montigue, whose bedroom is at the far end of it, and who has to pass that door to reach her own.
Not one of those is a crime. Not one of those is even unusual.
That is the entire architecture of it and I understood the whole thing standing in a linen room on the twenty-seventh of October.
