Publication order
The Lockwood & Co. books must be read in publication order for the main storyline, with the supplementary pieces placed after the central sequence for the clearest first reading, by following this sequence:[1-3]
| Order | Cover | Title | First published | Notes |
|---|---|---|---|---|
| 1 |
|
The Screaming Staircase | 2013[10] | Introduces the agency and ghost-hunting world. |
| 2 |
|
The Dagger in the Desk | 2013[11] | Works as an early case. |
| 3 |
|
The Whispering Skull | 2014[12-13] | Develops the skull, rival agencies, and occult mysteries. |
| 4 |
|
The Hollow Boy | 2015[14] | Builds on team relationships and Lucy’s changing Talent. |
| 5 |
|
The Creeping Shadow | 2015[15-16] | Continues from Lucy’s departure and expands the conspiracy. |
| 6 |
|
The Empty Grave | 2017[17-18] | Resolves the conflict surrounding the Other Side and Fittes. |
| 7 |
|
A Portland Row Christmas | 2023[2] | A supplementary holiday episode. |
| 8 |
|
The Apple Tree | 2024[3] | A retrospective Lockwood background piece. |

Chronological order
The publication order is the best approach for first-time readers. There is, however, a useful chronological order for readers who want to place the background and the late-series interlude in the internal sequence.[2-9]
This order moves The Apple Tree to the beginning because it concerns Anthony Lockwood’s childhood, before the formation of the agency seen in The Screaming Staircase. It also places A Portland Row Christmas before The Empty Grave, where it works as a late-series household interlude before the final confrontation. The trade-off is that this path gives background before its dramatic context is fully established.[2-9]
Alternatively, the Lockwood & Co. books may be read in chronological order, by following this sequence:[2-9]
| Order | Cover | Title | First published | Notes |
|---|---|---|---|---|
| 1 |
|
The Apple Tree | 2024[3] | Chronological prologue focused on Lockwood’s childhood and family background. |
| 2 |
|
The Screaming Staircase | 2013[10] | Properly introduces Lucy, the agency, and the working world of the series. |
| 3 |
|
The Dagger in the Desk | 2013[11] | Fits early in the team’s case history. |
| 4 |
|
The Whispering Skull | 2014[12-13] | Advances the skull, rival agencies, and occult-object storyline. |
| 5 |
|
The Hollow Boy | 2015[14] | Continues the agency’s internal changes and Lucy’s Talent. |
| 6 |
|
The Creeping Shadow | 2015[15-16] | Follows Lucy’s return and the widening institutional conspiracy. |
| 7 |
|
A Portland Row Christmas | 2023[2] | Works as a late-series interlude with the expanded Portland Row household. |
| 8 |
|
The Empty Grave | 2017[17-18] | Brings the main storyline to its final resolution. |

Works in sequence
The essential reading path is the main Lockwood & Co. storyline: the books that introduce the agency, develop its central relationships, expand the mystery of the ghost epidemic, and carry the larger conflict to resolution. They are The Screaming Staircase, The Dagger in the Desk, The Whispering Skull, The Hollow Boy, The Creeping Shadow, and The Empty Grave.[4-9]
The supplementary works, namely A Portland Row Christmas and The Apple Tree, add seasonal or retrospective material rather than forming the main plotline. They are most useful once the reader already understands the agency, the household, and the central characters. These additions are best suited to readers who want fuller coverage of the characters and world after completing the principal sequence.[2-3]
1. The Screaming Staircase

The Screaming Staircase (2013)[10] establishes the world of the series through Lucy Carlyle’s arrival in London and her work with Anthony Lockwood and George Cubbins. It introduces psychical investigation, haunted Sources, and the agency’s precarious independence.[4]
It also establishes the blend of casework and personal risk that shapes the series.[4]
2. The Dagger in the Desk

The Dagger in the Desk (2013)[11] follows Lockwood, Lucy, and George on a school haunting involving a violent spirit, a hidden source, and the agency’s usual blend of research and fieldwork. It features an early standalone case.[5]
However, it sits naturally after the first book because the team, their methods, and Lucy’s place within the agency are already established.[5]
3. The Whispering Skull

The Whispering Skull (2014)[12-13] expands the series beyond a single haunting by developing the skull in the jar, the agency’s rivalry with Quill Kipps, and the dangerous trade in occult objects. The book keeps the case-driven structure while strengthening the continuing elements, especially Lucy’s connection to the skull.)[6]
It also reveals more about the history behind powerful supernatural artifacts and their significance to the series.[6]
4. The Hollow Boy

The Hollow Boy (2015)[14] moves the series into more openly serial territory. The agency is now under strain from public success, overwork, a major ghost outbreak, and changing internal relationships.[7]
Lucy’s Talent becomes harder to manage, Holly Munro joins the household, and the ending changes the position of the central team going into the next installment.[7]
5. The Creeping Shadow

The Creeping Shadow (2016)[15-16] continues from Lucy’s separation from the agency and brings her back into Lockwood & Co. through a case that soon connects to a wider pattern of stolen relics, experiments, and institutional secrecy. It expands the importance of the skull, the Other Side, and the conflict with powerful organizations.[8]
These developments continue the main arc.[8]
6. The Empty Grave

The Empty Grave (2017)[17-18] is the culmination of the principal sequence. It brings together the team’s discoveries about the Other Side, the Fittes Agency, the Orpheus Society, Lockwood’s family history, and Lucy’s connection with the skull.[9]
This book builds on earlier developments and resolves the central narrative established across the preceding books.[9]
7. A Portland Row Christmas

A Portland Row Christmas (2023)[2] is a short holiday episode set around the familiar household at Portland Row. Its interest lies less in advancing the main supernatural conflict than in revisiting the group dynamic among Lucy, Lockwood, George, Holly, Kipps, Flo, and the skull, making it a supplementary piece best read after the characters are already known.[2]
It is best approached after the reader already knows the characters and their relationships. The story was posted on Jonathan Stroud’s X account.[2]
8. The Apple Tree

The Apple Tree (2024)[3] is a retrospective story focused on Anthony Lockwood as a child. It provides background on his family, his sister Jessica, and his early experience of ghosts.[3]
Because that material gains weight from knowledge supplied in the main sequence, it works better as supplementary context than as a first entry point, despite taking place earlier in Lockwood’s life. The story was posted on Jonathan Stroud’s X account.[3]
