A painted small suburban garden shop in Australia in 1946 seen from across the footpath: wooden trays of seedlings on trestles, terracotta pots stacked in a pyramid, bundles of bamboo stakes and hessian sacks under a blank painted fascia, and a lean weathered woman in a work dress and canvas apron holding a flat of seedlings

Trestles of seedlings out on the footpath, pots stacked in a pyramid, bundles of stakes, and half the shop belonging to a woman who arrived in September with a bank draft and her husband's tools.

The patch

The garden as witness. Hazel Drummond sells the Western District sheep farm her husband never came home to and buys half of Barrow's garden shop from Nell Barrow, another war widow — premises, customers and books included. Design commissions, the counter, and the indoor and balcony trade carry her into Bondi households at exactly the moment they are having something remade, which is exactly the moment what a place holds comes up out of it.

She is Burnley-trained, and ground keeps a better record than a doctor's certificate. Beds double-dug in August by somebody who does not know gardens. Nine foxgloves stripped to the crown, and the cut scars not all of one age. A maidenhair dead of dry soil in a flat that was watered four days ago.

The set

A painted 1940s garden shop interior: a worn timber counter with brass scales, a shallow drawer of unlabelled paper seed envelopes, a ball of twine, secateurs and glass jars of seed, with a big ruled ledger open on a desk against the back wall

Brass scales, a drawer of plain seed envelopes, and the ledger open on the counter with a column half totted. Nell's half of the business, and the best-informed counter in the district.

The cast

Told in one voice, Hazel's. In brief:

A painted private suburban garden in Australia in spring 1946 seen from a shaded side path: a deep flower border in full bloom against a paling fence, a turned bed of dark earth with a spade standing in it, a wheelbarrow and a brick path, and a glimpse of blue sea between roofs

A deep border in full spring bloom, a turned bed with the spade still standing in it, and a brick path to somebody else's verandah. She is here because she was hired. That is the whole of her authority, and it is enough.

The rhythm

Eight fair-play whodunits, one a season, and the seasons are canon: what is blooming, planted or traded in a book is what would be. Deaths are real, bloodless, and always discovered rather than shown. The clues are horticultural, and the reader gets every one of them when Hazel does.

Warm underneath and dry on top. Grief is ground rather than subject: it surfaces in hands and ledgers, never in rumination. The escalation is not bigger, it is more personal.

A painted plain community hall in Australia in 1946 set up for a women's meeting: two long trestle tables with white cloths, a large tea urn and rows of cups, folding chairs, a basket of craft work, a jug of garden flowers, and a timber noticeboard of blank pinned papers

Trestles, white cloths, the cups going out and the urn already on, craft work lifted from a basket and a jug of garden flowers. Twenty minutes before anyone else arrives, and by the end of the afternoon this room will know everything.

The question the series asks

What does the ground remember that the paperwork does not?

Where to start

One book a season, spring 1946 to winter 1948, so the order is the calendar. Each puzzle stands alone; the thread book five lights is the one book eight closes.

  1. The Spring Garden Murder — start here. A spring overhaul already on the books — deposit paid, beds double-dug in August, seed ordered — and the client dead at seventy and buried the week before. The ground argues with the certificate.
  2. The Summer Show Murder — a limb comes out of the old Moreton Bay fig above the show platform minutes before judging. Misadventure, the detectives write. Then she goes up the ladder herself.
  3. The Autumn Planting Murder — the district's gardening columnist pulls a dozen bulbs out of a new glasshouse bed, puts them in his handkerchief and walks out. Six days later he is dead in a lane, and the bulbs are not on the property list.
  4. The Winter Fernery Murder — the indoor round: twenty flats, one visit a Thursday. A maidenhair stripped to bare stems, the aspidistra a foot away untouched. A fortnight later they force that door. The series spends its one locked-room allowance here.
  5. The Spring Wedding Murder — three weeks to make and plant a bare block for a wedding, into the family her own Katina is marrying, which nobody at the shop mentioned. The hinge of the series.
  6. The Summer Memorial Murder — a two-woman shop wins the council's memorial-garden contract because a casual labourer stands on the made ground and tells them where the pit is. Then he stops turning up, which is what labourers do. One length of one bed settles far too much.
  7. The Autumn Foxglove Murder — five weeks to clear and replant two acres going to auction as fourteen blocks. The garden stopped twice; the second time was the week the old man died in his chair. Then she reads the foxgloves. This is the book where it turns physical.
  8. The Winter Camellia Murder — she has watered that house every Thursday for two years and can tell you when each fern was last touched. A returned man is in Long Bay for the robbery, and the plants disagree with the police.
