A Detective Inspector, a art collector who is supposed to be dead, and a luxury liner en route to New York. This is the fourth book in the series but can be read as a stand-alone, to note, I read this as a standalone and have not read any of the previous books before. The story starts off with DCI Warwick on a cruise, spending some time with his wife on their holiday trip, however he is dragged back into solving a murder on board (what can I say, these things have a way of finding people sometimes haha). DCI Warwick is part of the new Unsolved murders Unit ( a cold case squad that is dedicated to catching the criminals no one else can). His team each has their own particularly cases and the story is told from different POVs including that of the main villain, Miles Faulkner ( art collector who faked his death). There are many cases told in this story and it definitely gives off a collection of short stories vibe. The ending is a bit rushed but it does wrap up the book and case. While I didn’t particularly connect with any of the characters and found many cases and characters to sort of blend and not really make me care for them, maybe that’s just my case. Definitely give this book a go if you liked the the other books in the series.
