This is one of series of Welsh climbing mysteries featuring Shakespearean actor Abercrombie Lewker. Lewker is invited to a stay at an M.P.'s house near Snowdon but is soon involved in a murder investigation when is host, David Webhouse, is killed in an explosion. The plot holds together, and the solution is fair to the reader, but the story comes from the humdrum school of writing. The reprint is, of course, welcome but a little more attention could have been paid to proofing (and in particular air rifle). ( )
